The Laṅkāvatāra Sūtra (Sanskrit: लंकावतारसूत्र Laṅkāvatāra Sūtra; Traditional Chinese: 楞伽經; pinyin: léngqié jīng) 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 Laṅkāvatāra Sūtra draws upon the concepts and doctrines of Yogācāra and Tathāgatagarbha. 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. The sūtra asserts that all the objects of the world, and the names and forms of experience, are merely manifestations of the mind. The Laṅkāvatāra Sūtra describes the various tiers of consciousness in the individual, culminating in the “storehouse consciousness” (Skt. Ālayavijñāna), which is the base of the individual’s deepest awareness and his tie to the cosmic.
