The aim of this diploma thesis is to make a study of the śamatha-vipaśyanā theory on Śrāvakabhūmi in Yogacārabhūmi Śāstra, and it explores the establishment both in the theory and in the method of śamatha and vipaśyanā. It places emphasis on how to get through the practice of śamatha and vipaśyanā and will attain catvāri dhyānāny ārūpya-samāpattayaḥ of the laukika-mārga and the anāsrava-dharma of the lokottara-mārga in Śrāvakabhūmi. That is to say, it stresses how to set up its theory and sequences to the way of the enlightenment according to śamatha and vipaśyanā.
Firstly, it investigates śamatha in Śrāvakabhūmi; namely, it tries to understand the basic quality of śamatha and the practicing theory of śamatha-pakṣa by means of exploring the types of śamatha, the definitions of samāhita, the pūrva-gama of śamatha, and the approaches and prayoga of śamatha. Among them, Yogācāra proposes navākārā citta-sthitiḥ, nine stages from a-samāhita to samāhita and from shallowness to deepness, to be a practice of śamatha, which becomes a brief basis of practicing a śamatha’s learning. Secondly, on the basis of vipaśyanā, it explores the theory of ālambana, śruta-cintā-bhāvanā-mayyāḥ prajñāyāḥ and parīkṣya-artha. And it points out that Śrāvakabhūmi establishes the functional theory of practicing śamatha-vipaśyanā by way of vyāpya-ālambana. It also explores how to truly and clearly present the key to practicing śamatha-vipaśyanā with the help of the steps and sequences by transforming five carita-viśodhanam ālambanam into caturṇāṃ smṛty-upasthānānām and transforming ādhimokṣika-manaskāra into tattva-manaskāra.
Furthermore, it explores that exercising both śamatha and vipaśyanā is the key to āśraya-parāvṛtti and pratyakṣa-jñāna. And then, based on seven sapta manaskārāḥ of laukika-mārga and lokottara-mārga, besides exploring the acquiring sequences of the samāhita-bhūmika in laukika-mārga and the arhatva-phala in lokottara-mārga, it presents the similarities and differences of seven sapta manaskārāḥ between laukika-mārg and lokottara-mārga. And afterwards, by way of the laukika-mārg and the lokottara-mārga, it discusses whether Śrāvakabhūmi is a complete and inseparable śamatha-vipaśyanā practicing system or not.
Finally, on the basis of “yāvad-bhāvikatā and yathāvad-bhāvikatā” and “catasraḥ paryeṣaṇāḥ and catvāri yathā-bhūta-parijñānāni “, it explores how Śrāvakabhūmi and Bodhisattvabhūmi integrates śrāvaka śamatha-vipaśyanā and develops its own theory. In the beginning, it explores the process that how Śrāvakabhūmi integrates tattva-manaskāra in Abhidharmas with yāvad-bhāvikatā and yathāvad-bhāvikatā. Next, it explores how the vijñapti-mātra-jñāna theory is established by developing the catasraḥ paryeṣaṇāḥ and the catvāri yathā-bhūta-parijñānāni in Bodhisattvabhūmi as well as it explores how it integrates the practices of catus-kuśala-mūla and later on combines the trisvabhāva thoery into a unique and incomparable vijñapti-mātratā in Yogācāra.
