      THE SIGNIFICANCE OF `TATHAGATAGARBHA`:
        A POSITIVE EXPRESSION OF `SUNYATA`

              HENG-CHING SHIH


             The well-known motto of Ch'an Buddhism is that
        "perceiving the true self, one becomes a Buddha."
        The "true self" signifies the Buddha nature inherent
        in all sentient beings. The discovering of the "true
        self" has become the single most important pursuit
        of the Buddhist, especially in Sino-Japanese
        Buddhism. On the contrary, early Buddhism teaches
        that ultimately no substantial self (i.e.,
        `anatman`) can be found, since the self is nothing
        but the union of the five aggregates. Modern
        Buddhologists as well as the Buddhists have been
        intrigued by the inconsistency that one single
        tradition teaches both that there is no self on the
        one hand, and that the goal of religious life is to
        discover the true self, on the other hand.

             The big questions concerning these two
        contradictory doctrines include: How did they
        develop during the course of Buddhist history? How
        can they be reconciled? Are these two ideas
        actually as contradicting as they appear to be? Is
        the concept of the Buddha nature an outcome of the
        influence of other Indian religious thought upon
        Buddhism? It is out of the scope of this short
        paper to answer all these questions. Therefore, this
        paper will deal with the antecedent and synonymous
        concept of the Buddha nature, that is, `tathagata-
        garbha`(`ju lai tsang`). Specifically, this paper
        will examine the meaning and significance of the
        `tathagatagarbha` (Buddha nature) based on three
        `tathagatagarbha` texts and argue that the

                             228頁

              `tathagatagarbha`/Buddha nature does not
        represent a substantial self (`atman`); rather, it
        is a positive language and expression of `sunyata`
        (emptiness) and represents the potentiality to
        realize Buddhahood through Buddhist practices. In
        other words, the intention of the teaching of
        `tathagatagarbha`/Buddha nature is soteriological
        rather than theoretical.

             The term "`tathagatagarbha`" is generally taken
        as to mean that the "garbha" of a `Tathagata` exists
        in all sentient beings without exception, and though
        temporarily contaminated by adventitious defilement
        (`agantukaklesa`), it is the cause which eventually
        leads sentient beings to enlightenment. The notion
        of the `tathagatagarbha` can be traced to a luminous,
        inherently pure mind (pabhassar citta) found in
        the `Anguttara-nikaya` (1:5):
          Pabhassarm `idam` bhikkhave cittam `tan` ca kho
          `agantukehi` upakkilesehi `upakkilitthan` ti
          pabhassaram idam bhikkhave `cittam tan` ca kho
          `agantukehi` upakkilesehi vippamuttan ti
          Oh! `Bhiksus`. The mind is pure; it is defiled
          by The adventitious defilement.
          Oh! `Bhiksus`. The mind is pure; it obtains
          liberation
          Through the adventitious defilement.

             When the original pure mind came to be regarded
        as something capable of growing into Buddhahood,
        there was the `tathagatagarbha` doctrine. Although
        the concept of an intrinsically pure mind exists in
        the Nikaya Buddhism, many Buddhologists, such as
        Wayman,(1)Paul,(2) Yin-shun(3) think that

        the `tathagatagarbha` thought was originated from
        the `Mahasamgika`, but was rejected by the
        `Theravada`. This theory is also held by Mizuno who
        points out that the pure mind (`pabhassarcitta`)
        articulated in the Nikaya Buddhism is not totally
        identical with the original pure mind
        (`prakrtivisuddhi-citta`) articulated in the
        `Tathagatagarbha` doctrine, for Mizuno asserts that
        the former is static whereas the latter is dynamic
        in that it is capable of eradicating defilement.(4)
        At any rate, the relationship between pure mind and
        the adventitious defilement appears to have been
        wholly adopted by the `Mahasamghika` and later by
        the `Mahayana`.

             According to I-tsing's (義淨) Nan-hai-chi-kuei
        Nei-fa-chuan (The record of the Buddhist kingdoms in
        the Southern Archipelago 南海寄歸內法傳), "the
        so-called `Mahayana` (in India) is no more than the
        two: one `Madhyamika`, the other `Yogacara`."(5)
        Although it is commonly held that the `Madhyamika`
        and `Yogacara` were the two major philosophical
        schools in Indian `Mahayana` and although it might
        be true that `tathagatagarbha` thought never formed
        an academic school in India, this does not mean that
        the `tathagatagarbha` doctrine never played a
        significant role in the development of Indian
        Buddhist thought.(6) This is attested by the fact
        that there are

        6. There is no evidence that the `Tathagatagarbha`
           formed a school in India. For one thing there
           never existed a patriarchal figure in the
           `tathagatagarbha` as `Nagarjuna` in `Madhyamika`
           and `Asanga` in `Yogacara`. However, Fa-tsang
           identified a "ju-lai-tsang yuan-chi tsang", i.e".
           "a school of `Tathagatagarbha-pratityasamut-pada`".
           Furthermore , Takasaki identifies
           `Tathagatagarbha-vada` in

                              230頁

        many `tathagatagarbha` scriptures composed in India
        approximately from the third to the sixth century,
        such as the `Tathagatagarbha-sutra`,
        `Maha-parinirvana-sutra`,
        `Anuatyapurn-atvanirdesa-sutra`,
        `Srimaladevisimhanada-sutra`, `Lankavatara-sutra`,
        Rotnagotravibhaga, Buddha-nature Treatise, etc.

             Since the beginning of this century, many
        `Buddhologists` have become interested in the
        `Tathagararbha` doctrine and have shed new light on
        tathagatagarbha thought. However, their studies,
        especially on the Ratnagotravibhaga, lead to two
        different interpretations of the `tathagatagarbha`
        doctrine, i.e., `tathagatagarbha as a monistic
        doctrine, and `tathagatagarbha` as the embodiment of
        the principle of dependent co-arising
        (`pratityasamutpada`) or `sunyata`, following the
        traditional `Mahayana` Buddhist lines.

             Obermiller, who maintains the `Tathagatagarbha`
        as monistic, in the introduction to his translation
        of the Ratnagotravibhaga, says that in this text,
        "we see that Aryasanga has come to a fully monistic
        and pantheistic conception" and that
                The central point of this most developed
                theory is the teaching that the fundamental
                element of Buddhahood, the essence of the
                Buddha in a living being represents an eternal,
                immutable (`asamskrta`) element, which is
                identical with the monistic Absolute and is
                unique and undifferentiated in everything that
                 lives."(7)

             Takasaki, `an` eminent scholar of the
        `tathagatagarbha` doctrine, asserts that the
        `tathagatagarbha` thought holds some monistic
        element. He says,

          When Buddhism developed itself into `Mahayana`
          Buddhism, it could not but take the appearance of
          Monism as a result of Absolutization of the Buddha,
          and approach the Upanishadic thinking in its
          philosophy....for explaining the possibility of
          anyone's acquiring the Buddhahood, the Monistic
          philosophy was used as the background. In this
          last point lies the significance of the
          `tathagatagarbha` theory of this text. This
          theory is in one sense an inevitable result of the
          development of Mahayanistic monism in its
          religious expression."(8)

        Although Takasaki notes that there is a difference
        between the nature of monism in the Ratnagotravibhaga
        and in the Upanishads, for the Absolute taught in the
        Ratnagotravibhaga is the manifestion of `sunyata`
        which is of a quite different character from the
        substantial Absolute of the Upanishads, still he
        believes "there was an influence from the
        Upanishadic thought for the `astivada` of the Ratna
        to establish its monistic doctrine."(9)

             The reason for those scholars' holding the
        `tathagatagarbha` doctrine as monistic is that they
        base their interpretation on passages in various
        `tathagatagarbha` literature which assert the
        equivalence of the `tathagatagarbha` to terms with
        all-pervading character, such as `tathata`,
        `dharmakaya`, `dharmadhatu`, etc., which describe
        the `tathagatagarbha` as being eternal (nitya) and
        immutable (`atman`), which assert the fundamental
        purity

        of the `tathagatagarbha` (equating the
        `tathagatagarbha` as `prakrtiparisuddhi-citta`, the
        original pure mind), and which assert that the
        `tathagatagarbha` functions like a first cause from
        which the phenomenal reality emanates.

             However, if we examine more carefully the
        `tathagatagarbha` doctrine, we will find that it can
        be interpreted as an expression of the concept of
        `pratityasamutpada` and `sunyata`. Yamaguchi(10) and
        Ogawa(11) follow this traditional line.

             Interestingly, modern Buddhologists are not
        alone in their puzzle about the question of whether
        the `tathagatagarbha` represents a kind of
        Upanishadic `atman`. Bodhisattva `Mahamati` in the
        `Lankavatarasutra` raised a question concerning this
        issue. He said to the Buddha,

          Now the Blessed one makes mention of the
          `tathagatagarbha` in the sutras, and it is
          described by you as by nature bright and pure, as
          primarily unspotted, endowed with the thirty-two
          marks of excellence, hidden in the body of every
          being like a gem of great value....it is described
          by the Blessed One to be eternal, permanent,
          auspicious and unchangeable. Is not this
          `tathagatagarbha` taught by the Blessed One the
          same as the ego-substance taught by the
          philosophers (tirthikas)?(12)

        In this passage, the Buddha clearly identified the
        `tathagatagarbha` with emptiness, markless,
        `tathata`, etc., meaning that the `tathagatagarbha`
        is without any substantial entity. Then the question
        arises: if the `tathagatagarbha` is empty by nature
        , why the Buddhas teach a `tathagatagarbha`
        possessing all positive

        attributes, such as eternal (nitya), self (`atman`),
        bliss (sukha) and pure (subha)? The Buddha goes on
        to answer this question,

          The reason why the `Tathagatas` who are Arhats and
          fully enlightened Ones teach the doctrine pointing
          to the tathagatagarbha which is a state of
          non-discrimination and imageless, is to make the
          ignorant cast aside their fear when they listen to
          teaching of egolessness. It is like a potter who
          manufactures various vessels out of a mass of clay
          of one sort by his own manual skill and labour
          ....that the `Tathagatas` preach the egolessness
          of things which removes all the traces of
          discrimination by various skillful means issuing
          from their trancend-ental wisdom, that is,
          sometimes by the doctrine of the `tathagatagarbha`
          , sometimes by that of egolessness....Thus,
          `Mahamati`, the doctrine of the `tathagatagarbha`
          is disclosed in order to awaken the philosophers
          from their clinging to the idea of the ego.
          Accordingly, `Mahamati`, the `Tathagatas` disclose
          the doctrine of the `tathagatagarbha` which is thus
          not to be known as identical with the
          philosopher's notion of an egosubstance. Therefore
          ,  `Mahamati`, in order to abandon the
          misconception cherished by the philosophers, you
          must depend on the `anatman-tathagatagarbha`.(13)

        It is pointed out in this passage that the
        `tathagatagarbha` is empty in its nature yet real;
        it is `Nirvana` itself, unborn, without predicates.
        It is where no false discrimination (nirvikalpa)
        takes place. There is nothing here for the Buddhas
        or Bodhisattvas to take hold of as an `atman`. They
        have gone beyond the sphere of false discrimination
        and word. It is due to their wisdom and skillful
        means (`upaya`) that they set up all kinds of names
        and phrases in order to save

                             234頁

        sentient beings from mistaken view of reality. In
        other words, it is exactly to help sentient beings
        case away their fear of `anatman` that the
        `tathagatagarbha` with positive attributes (i.e.,
        `asunya-tathagatagarbha`不空如來藏) is taught, and
        at the same time it is to get rid of the clinging of
        `atman` that the `anatman-tathagatagarbha`(無我如來
        藏) is taught. Thus it is clear that the
        `tathagatagarbha` is not an Upanishadic `atman`. Now
        let's turn to examine how Yamaguchi and Ogawa who
        hold this traditional line interpret this doctrine.

             Yamaguchi points out that the statement in the
        Ratnagotravibhaga, "O Noble youth, such is the
        essential nature of the dharma (`dharmanam
        dharmata`), whether the `Tathagatas` appear in the
        world, or whether they do not, these living beings
        are always possessed of the matrix of the
        `Tathagata`" (15) is parellel to the statement found
        in the Sammyutta-nikaya "Whether the `Tathagatas`
        were to appear in the world, the theory of
        `pratitysamutpada` remains."(16) Here we see the
        `tathagatagarbha` was considered as a valid
        principle as `pratitysamutpada`. Thus Yamaguchi
        holds that the most important point in expounding
        the `tathagatagarbha` in the Ratnagotravibharga is
        that "the `pratitysamutpada` is the
        `tathagatagarbha`." (engi sunawachi nyoraizo 緣起即
        如來藏)(17).

             Ogawa, following the same position, interprets
        the `tathagatagarbha` according to the commentary of
        the `Ratnagotravibhaga` by the Tibetan master,
        Dhar-ma rin-chen. He argues that the
        `tathatagatagarbha` is essentially the same as
        `sunyata`, and also it has the `sunyata` nature
        which allows the

        mind to understand `sunyata`. The crucial point of
        this interpretation centers on the passage "all
        sentient beings are possessed of the
        `tathagatagarbha`" in the Ratnagotravibhaga. It
        expounds three `svabhavas` of the `tathagatagarbha`
        to justify the above passage. According to Dhar-ma
        rin-chen, the three `svabhavas` are ways of
        explaining the `tathagatagarbha` form three
        perspectives: from the perspective of the result
        level of the `Tathagata`, from the perspective of
        the nature of the `Tathagata` and form the
        perspective of the cause of the `Tathagata.`(18)

             (1) `Dharmakaya-svabhava`: from the
        perspective of the result level of the `Tathagata`.
        The `Dharmakaya-svabhava` means that the
        `Dharmakaya` of the `Tathagata` penetrates all
        sentient beings. According to Takasaki, this first
        `svabhava` is derived from the `
        Tathagatotpattisambhavambhava-parivarta` of the
        `Avatamsaka-sutra` as cited in the Ratnagotravibhaga
        : "There is no one among the groups of sentient
        beings in whose body the wisdom of the `Tathagata`
        does not penetrate at all."(19) It seems that when
        "the `dharmakaya` of the `Tathagata` pervades" is
        taken to mean that there is no part of the universe
        where the substantial entity is not present, it
        could fall into a monistic interpretation. However,
        according to Dhar-ma rin-chen, the `Dharmakaya` is
        explained as having two aspects: 1) `Dharma-dhatu`,
        the perfectly pure realm of ultimate truth itself,
        in which "dharma" means "teaching" and "`dhatu`"
        means "cause". Therefore, the `Dharmadhatu` refers
        to the supreme truth which is the cause of the
        teaching, and 2)

        the nature outflow (`nisyanda`) of wisdom. Thus we
        see whereas the former aspect of the `Dharmadhatu`
        refers to the truth realized by the Buddha, the
        static aspect of the `Tathagata's` enlightenment,
        the later refers to the dynamic aspect of the
        `Tathagata's` enlightenment, i.e., teaching the
        Dharma. This is to say that the Buddhadharma, or the
        teaching, spontaniously flows out of the
        `Tathagata's` compassion for the benefit of sentient
        beings. Therefore, when the Ratnagotravibhaga states
        that "all beings possess the `tathagatagarbha`"
        (because the `Dharmakaya` of the `Tathagata`
        penetrates all sentient beings), it simply means
        that sentient beings are able to hear the pure
        dharmas and are everywhere and constantly permeated
        by them, as the nesessary outflow of the
        `Dharmadhatu`.(20) In other words, the universality
        of the `Tathatagatagarbha` expressed here refers to
        the potential capacity within living beings to be
        effected by the teaching of the Buddha and hence
        does not have a notion of a substantial entity.

             2) `Tathata-svabhava`: from the perspective of
        the nature of the `Tathagata`. This
        `tathata-svabhava` means that the `tathata` of the
        `Tathagata` is not different from the `tathata` of
        the sentient beings. The underlying principle of
        this identity of the `tathata` of the `Tathagata`
        and that of sentient being is `sunyata`. Since the
        ultimate nature of both the `Tathagata` and sentient
        beings are `sunyata`, they are seen to be
        undifferentiated. The only difference is that when
        the `tathata` is associated with defilement, it is
        called the "`tathagatagarbha`" or `samala tathata`
        (of sentient beings), and when the defilement
        ────────────

                             237頁

        is removed, it becomes `nirmala tathata` (of the
        `Tathagata`). Yet they are essentially identical.
        Therefore, one says that all sentient beings possess
        the `tathagatgarbha` when referring to the existence
        of the `sunyata` nature of living being's mind which
        is essentially free of defilement. Again no notion
        of immutable substance should be asserted.

             3) `Gotra-svabhava: from the perspective of
        the cause of the `Tathagata`. This `gotra-svabhava`
        means that the gotra (seed nature) of the
        `Tathagata` exists in all sentient beings. The gotra
        in this context is explained accroding to the
        two-fold structure: (1) the `prakrtistha-gotra`
        (innate gotra), and (2) the `samudanilagora`
        (acquired gotra). According to Dhar-ma rin-chen,

          Based on the innate gotra, the first body, which
          is `Dharmakaya`, is obtained. Based on the
          acquired, perfected gotra, the later two form
          bodies (`sambohogakaya` and `nirmanakaya`) are
          obtained.(21)
        The `prakrtistha` gotra which obtains the
        `dharmakaya`, does so on the basis of the wisdom
        (`prajna`) through which insight into the reality of
        all dharmas is attained. According to Dharma
        rin-chen, the `prakrtistha` gotra is the primary
        meaning of the `tathagatagarbha`, because it is
        identified with `sunyata` and as such the primary
        "cause" of Buddhahood.
             The `samudanita` gotra which obtains
        `sambhogakaya` and `nirmanakaya`, does so on the
        basis of vigorous practices and the accumulation of
        innumberable merits and thus is the productive
        "cause" of Buddhahood. The `samudanita` is called
        the uttara, or ultimate, because it signifies the
        central theme of general `Mahayana` practice, that
        is, "wisdom (`Dharmakaya`) becomes compassion
        (`rupakaya`)(22). In other words, within

                             238頁

        the very meaning of gotra is experssed the movement
        from `prajna` to `karuna`. This might be called
        hsia-huei-hsiang (下迴向), a down-ward
        transformation or `tatha-agata`, i.e., returning
        from the realm of enlightenment to that of this
        world of sentient beings─a process of enlightening
        others, after the socalled shan-huei-hsiang (上迴向)
        , an up-ward transformation or `tatha-gata`, i.e.,
        striving for the realm of enlightenment from the
        realm of this world of sentient beings, a process of
        enlightening oneself. However, this "two-way
        traffic" process should not be seen as two
        distinctive and separated processes; rather, they
        are non-dual, interrelated and inter-dependent.

             Based on the commentary of Dhar-ma rin-chen, we
        can conclude that the real purpose of the passage
        "the gotra of the `Tathagata` exists in all sentient
        beings" is to articulate bodhisattva practices based
        on wisdom. This is supported by the structure of the
        Ratnagotravibhaga, which is arranged by the
        following order: 1. Buddha, 2. Dharma, 3. Sangha,
        4. `Dhatu`, 5. Bodhi, 6. `Guna` (merits) and Karma
        (act). The seven `vajrapadas` are expalined in terms
        of cause, condition and result. "`Dhatu`" is the
        "cause"; bodhi, `guna`, and karma are the
        "conditions" through which the three jewels (of the
        Buddha, Dharma and Sangha) as "result" are
        manifested. As kiyota says that the wisdom, merits
        and practice of a Bodhisattva constitute the
        condition through which the "Buddha-is-caused". The
        expression "Buddha-is-caused", or "Buddha-caused" is
        derived from `Buddha-dhatu`. It is employed
        synonymously with the `tathagatagarbha`. As Kiyota
        rightly points out, the term "cause" here does not
        refer to a first cause (i.e., a substance or a
        physical entity), but symbolically as a potential (a
        principle) which is empirically

                             239頁

        revealed through a set of conditions─wisdom, merits
        ,and practices.(23) In other words, the
        `tathagatagarbha` as a potential inherent in the
        human consciousness can only be realized through
        Bodhisattva practices.

             The above arguments are mainly based on the
        Rathagotravibhaga. At least two other
        `Tatnagatagarbha` related `sutras` also support this
        viewpoint. One is the Buddha Nature Treatise(24) and
        the other the `Mahaparinirvana sutra`(25).

             In the Buddha Nature Treatise, the author gives
        five reasons to the question why the Buddha spoke of
        Buddha nature. They are (1) to cause sentient beings
        to depart from inferior mind, (2) to leave behind
        arrogance, (3) to get rid of delusion, (4) to keep
        away from slandering the truth and (5) to sever the
        attachment to self(26). By overcoming these five
        shortcomings, one gives rise to five virtues, namely
        , diligent mind, reverence, widom (`prajna`)
        knowledge (`jnana`) and compassion (`karuna`).
        Clearly, right from the beginning, the author does
        not try to establish that the Buddha nature stands
        for something substantial. Rather, he points out the

       24. Traditionally, Fo Hsing Lun (The Buddha Nature
           Treatise) is attributed to Vasubandha and
           translated into Chinese by `Paramartha`. Some
           Buddhologists, for example, Takasaki, suspect
           that it was actually written by `Paramartha`.
           However, this is still an unresolved issue. At
           any rate, this text represents the Yogacarin view
           concerning the Buddha nature.
       25. This is the `Mahayana` version of the Buddha's
           `Parinirvana`. Its content concentrates mainly on
           the `Mahayana` doctrines such as the eternal
           nature of Buddhahood rather than on the
           description of the last days of the Buddha.

        soteriological function of the teaching of the Buddha
        nature.

             Delusion refers to the two erronous views of
        the substential existence of both person (`atman`)
        and things (dharma). Ignorant actions arise from
        these two attachments to the self and external
        things which prevent human beings from perceiving
        the truth. To the author of the Buddha Nature
        Treatise, the truth is nothing but the Buddha nature,
        for "Buddha nature is the Thusness revealed by the
        twin emptiness of person and things."(27) Thus it
        is said that "if one does not speak of Buddha
        nature, then one does not understand emptiness and
        consequently will cling to reality and slander
        Thusness."(28) Since the Buddha nature is the
        implementation of emptiness, it can be any thing but
        an entity.

             Furthermore, in the chapter of expounding the
        nature of Buddha nature, the author identified
        Buddha nature with the `Dharmakaya`, which is
        characterized with four virtues (`guna`). One of
        them is "self" (`atman`). This "self" is immediately
        identified with the perfection of non-self
        (`anatman-paramita`無我波羅蜜). How can the self be
        at the same time the perfection of non-self? The
        author explains,

          All the heterodox, in their various ways, conceive
          and grasp a self in those things which lack self,
          namely, the five skandhas─form, etc. Yet these
          things such as form, etc. differ from what one
          grasps as the mark of self; therefore, they are
          eternally lacking in self [However] with the
          wisdom of Thusness (chen ju chih真如智). all
          Buddhas and bodhisattvas realize the perfection of
          non-self (`anatman-paramita`) of all things
          ───────────

         28. Ibid.

                             241頁

          Since this perfection of non-self and that
          which is seen as the mark of not-self are not
          different, the `Tathagata` says that this mark of
          the eternal not-self is the true, essential nature
          (chen t'i hsing 真體性) of all things, therefore.
          it is said that the perfection of not-self is
          self. As the `sutra` verse says,
              Already the twin emptiness [of person and
              thing] is pure!
              [In this] is realized the not-self, the
              supreme self, Since the Buddha realizes the
              pure nature (hsing性). Not-self turns on
              itself (chuan轉) and becomes self.(29)

             It is evident from this explanation that the
        teaching of Buddha nature is the instrument employed
        along with `prajna` to realize the true, essential
        nature of all dharmas, namely, the non-self.
        Soteriologically speaking, `tathagatagarbha/Buddha`
        nature also functions as an active skillful means,
        for it is reiterated in several `tathagatagarbha`
        texts that `tathagatagarbha` is the basis of
        `samsara` and `nirvana`. That is to say without
        `tathagatagarbha/Buddha` nature, sentient beings
        would neither arouse aversion to `samsara` nor
        desire for `nirvana`. Therefore, `tathagatagarbha`
        is active, not static. In other words, it represents
        actions of practice, rather than an monastic
        substance.

             This interpretation can be further attested by
        the three causes of the Buddha nature explained in
        the Buddha Nature Treatise. The Buddha nature
        consists of three causes: (1) "deserved" cause (應
        得因), (2) the cause of intensified effort (加行因),
        and (3) the casue of fulfillment (圓滿因).(30) The

        three-cause schema signifies that depending on the
        "Thusness manifested by the twin emptiness (i.e.,
        Buddha nature)", and through the intensified effort
        of Buddhist practices, one "should obtain" or
        "deserves" the fulfillment of Buddhahood. Apparently
        , the pivot of the triple cause is the cause of
        intensified practice, for it plays the role of
        activating the potentiality to realize the Buddha
        nature.

             As we know, the `Mahaparnirvana-sutra` is one
        of the most important `sutras` which articulate the
        concept of Buddha nature. Just as the
        Ratnagotravibhaga claims that all sentient beings
        possess the `tathagatagarbha`, so the
        `Mahaparinirvana Sutra` teaches that sentient beings
        have the Buddha nature. In explaining what it means
        by sentient beings' having the Buddha nature, the
        `Mahaparinirvana Sutra` distinguishes three
        different ways of understanding the term "to have",

          Good son, there are three ways of having: first,
          to have in the future, Secondly, to have at
          present, and thirdly, to have in the past. All
          sentient beings will have in future ages the most
          perfect enlightenment, i.e., the Buddha nature.
          All sentient beings have at present bonds of
          defilements, and do not now possess the thirty-two
          marks and eighty noble characteristics of the
          Buddha. All sentient beings had in past ages deeds
          leading to the elimination of defilements and so
          can now perceive the Buddha nature as their future
          goal. For such reasons, I always proclaim that all
          sentient beings have the Buddha nature.(31)

        having Buddha nature with the third way of having,
        i.e., having in the future, it is again a proof that
        the teaching of the universal Buddha nature does not
        intend to assert the existence of substantial,
        entity-like self endowed with excellent features of
        a Buddha. Rather, Buddha nature simply represents
        the potentiality to be realized in the future.

             Elsewhere in the `Mahaparinirana Sutra`, Buddha
        nature is defined as the ultimate emptiness and the
        Middle Way. It says,

          Good son, Buddha nature is the ultimate emptiness
          ,which is `prajna` itself. [False] emptiness means
          not to perceive emptiness or non-emptiness. The
          wise perceive emptiness and non-emptiness,
          permanence and impermanence, suffering and
          happiness, self and non-self. What is empty is
          `samsara` and what is not empty is great
          `nirvana`.... Perceiving the non-self but not the
          self is not the Middle Way. The Middle Way is
          Buddha nature.(32)

        The essential point of this passage is that true
        emptiness, or in this case Buddha nature, trancends
        any dictomony─being and non-being, self and
        non-self, suffering and happiness, etc. Ordinary
        people and the heterodox see only the existence of
        self, while `Sravakas` and Pratyekabuddhas perceive
        only the non-self, but not the existence of a self.
        Clinging to one extreme or the other, they cannot
        realize the ultimate, and true emptiness and
        consequently cannot realize the Middle Way. Without
        the Middle Way, they are not able to comprehend
        Buddha nature. Trying to lessen the monistic flavour
        of the Buddha nature, the `Mahaparinirvana Sutra`
        interprets Buddha nature as both emcompassing and
        transcending the notions of self
        ────────────
       32. T. 12, p. 523b.

                             244頁

        and non-self. It makes the doctrine of the Buddha
        nature adhere closely to the Buddhist teaching of
        non-duality and the Middle Way. Thus Buddha nature
        should not be treated as equivalent to the monistic
        absolute. If it does seemly indicate the presence of
        a substantive self, it is actually a positive
        expression of emptiness.

             In conclusion, when we try to interpret the
        thought of the `tathagatagarbha`, we should keep
        several points in mind: (1) The `tathagatagarbha`
        symbolizes the potential for enligh-tenment (a
        principle) rather than a material "essence" of
        ultimate truth, because (2) the `tathagatagarbha` is
        based on the framework of the `Mahayana` doctrine of
        `sunyata-pratitys-amutpada`. (3) The development of
        the `tathagatagarbha` doctrine signifies the ability
        of a religious tradition to meet the spiritual needs
        of the masses aiming at a given time. That is to
        say the `tathagatagarbha` thought was formed as an
        positive soterio-logical approach to counteract the
        "`sunyam sarvam`" (all is empty) view. The
        `tathagatagarbha` which strongly articulates a
        devotional and experiential approach to salvation
        provides much to the hope and aspiration of the
        people at large.

             It is this positive aspect that was taken up
        and strongly emphasized in Chinese Buddhism. (4) The
        `tathagatagarbha` doctrine is employed as a
        skill-in-means (`upaya`). This does not necessarily
        mean that the theory of the `tathagatagarbha` is
        neyartha, a teaching requiring further
        qualifications; rather, it is a skill-in-means in
        that it is taught to suit the needs of a certain
        kind of people and circumstances. This is why it is
        said in the `sutra` that in order to teach the
        emptiness of all dharmas, the Buddhas preach
        sometimes by the doctrine of the `tathagatagarbha`,
        and sometimes by that of emptiness. Thus

                             245頁

        it is better to take the `tathagatagarbha/Buddha`
        nature as representing "profound existence" (妙有)
        derived from "true emptiness" (真空) rather than as
        a monistic self.
