The ''Laṅkāvatāra Sūtra'' (Sanskrit: ; ) is a sutra of Mahāyāna Buddhism. The sūtra recounts a teaching primarily between the Buddha and a bodhisattva named Mahāmati ("Great Wisdom"). The sūtra is set in Laṅkā, the island fortress capital of Rāvaṇa, the king of rākṣasas. The title of this text roughly translates as "Scripture of the Descent into Laṅkā." The ''Laṅkāvatāra Sūtra'' figured prominently in the development of Chinese, Tibetan and Japanese Buddhism. It is notably an important sūtra in Chan Buddhism and its Japanese version, Zen. ==Sūtra doctrine== The ''Laṅkāvatāra Sūtra'' draws upon the concepts and doctrines of Yogācāra and Buddha-nature.〔Youru Wang, ''Linguistic Strategies in Daoist Zhuangzi and Chan Buddhism: The Other Way of Speaking.'' Routledge, 2003, page 58.〕 The most important doctrine issuing from the ''Laṅkāvatāra Sūtra'' is that of the primacy of consciousness (Skt. ''vijñāna'') and the teaching of consciousness as the only reality. In the sūtra, the Buddha asserts that all the objects of the world, and the names and forms of experience, are merely manifestations of the mind: Because the world is seen as being "mind-only" or "consciousness-only", all phenomena are void, empty of self (atman) and illusory: The ''Laṅkāvatāra Sūtra'' describes the various tiers of consciousness in the individual, culminating in the tathagatagarbha (womb of the Buddhas) or "storehouse consciousness" (Skt. Ālayavijñāna), which is the base of the individual's deepest awareness and his tie to the cosmic. However, the Buddha makes clear that the Buddha-nature is not a self (atman) and is empty of self-nature. He states that it is merely a useful means (upaya) of teaching the dharma to others: The tathagatagarbha or "Buddha-nature" doctrine has been interpreted as an expression of the doctrines of pratītyasamutpāda "dependent origination" and emptiness. While seemingly monistic in nature, describing the tathagatagarbha as eternal (nitya) and immutable ('atman'), this doctrine is ultimately based on emptiness. According to Japanese scholar Yamaguchi Susumu, the most important point in the tathagatagarbha literature is that "the 'pratitysamutpada' is the 'tathagatagarbha'."〔Heng-Ching Shih, (The Significance Of 'Tathagatagarbha' -- A Positive Expression Of 'Sunyata' )〕 Likewise, Ichijo Ogawa, argues that 'tathatagatagarbha' is basically equivalent to emptiness and the nature of the mind which allows it to understand emptiness. This interpretation is based on a passage from the ''Ratnagotravibhāga'', which states that "all sentient beings are possessed of the 'tathagatagarbha'".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Laṅkāvatāra Sūtra」の詳細全文を読む スポンサード リンク
