『大乗荘厳経論』第IX章における「法界清浄の六義」理解 ー bauddhadhātuとdharmadhātuの意図する構造 ー=The "Six Meanings of dharmadhātuviśuddhi " in the Mahāyānasūtrālaṃkāra Chapter IX —The Structure of Chapter IX Implied by the Concepts of " bauddhadhātu " and "dharmadhātu"
In the Yogācāra school, the kernel of enlightenment is expounded as dharmadhātuviśuddhi in the Mahāyānasūtrālaṃ kāra Chapter IX.56-59. It has six meanings: [1] essence (svabhāva IX.56), [2] cause (hetu IX.57ab), [3] effect (phala IX.57cd), [4] act (karman IX.58ab), [5] connection (yoga IX.58cd) and [6] function (vṛ tti IX.59ab). These six meanings are not simply placed side-by-side but complexly interrelated each otheṛ Namely, [6] vṛtti further has three meanings: [i] essence (svabhāva), [ii] enjoyment of dharma (dharmasaṃ bhoga) and [iii] transformation (nirmān. a). And [i] svabhāva corresponds to [1] svabhāva (IX.56); [ii] dharmasaṃ bhoga to [2] hetu and [3] phala (IX.57); and [iii] nirmān. a to [4] karman and [5] yoga (IX.58). [6] vṛ tti is the function of dharmadhātu-viśuddhi, which is called bauddha-dhātu in IX.55. In other words, “bauddha” is “viśuddhi” and “dhātu” is “dharmadhātu”. In the MSA, the word “bauddha” appears only in four verses of chapter IX; namely, A bauddha-dharma (IX.10), [B] bauddha-citta-jñāna (IX.25), [C] bauddha-vibhutva (IX.45) and [D] bauddhadhātu (IX.55), which seems to comprise the preceding three A, B & C]. [A bauddha-dharma refers to the contents of IX.1-11, [B] bauddha-citta-jñāna those of IX.18-25, and [C] bauddhavibhutva those of IX.27-55. They are respectively recapitulated as the three meanings of [6] vṛ tti (viz., [i], [ii], [iii]). Furthermore, [6] vṛ tti corresponds to āśrayaparāvṛ tti that is suggested by IX.55 together with IX.11, 26 and 41-48. Thus, [A], [B] and [C] are based on āśrayaparāvṛ tti and recapitulated as [D] bauddha-dhātu. In other words, enlightenment in the Mahāyānasūtrālaṃ kāra is epitomized as [6] vṛ tti of dharmadhātu-viśuddhi (IX.59cd) and is essentially āśrayaparāvṛ tti. As I mentioned above, [6] vṛ tti comprises the other five meanings of dharmadhātu-viśuddhi, viz., [1], [2], [3], [4] and [5]. [6] vṛ tti further has three meanings, viz., [i], [ii] and [iii], which immediately brings in the exposition of the three bodies (buddhakāya) and the four wisdoms (buddhajñāna) of the Buddha. The names of the three bodies, in particular, are derived from the three meanings of [6] vṛtti. It finally amounts to dharmadhātuviśuddhi that recapitulates the contents of IX.1-55.
