Toh 107The Sūtra on the Descent into Laṅka

An Explanation of the Sutra of the Descent into Lanka (Laṅkāvatārasūtra)

Context

The Sutra of the Descent into Lanka (Laṅkāvatārasūtra, Toh 107 in the Northern canon) is a Mahayana sutra with a special position in the Buddhist scholastic traditions of East Asia. “Lanka” refers to the island of Sri Lanka, where the Blessed One taught the Dharma; “avatara” means “descent,” symbolizing the descent of the Buddhadharma from the transcendent realm into the consciousness of sentient beings.

This scripture is often regarded as a canonical text of the Chan/Zen tradition, especially of the Mind-Only (Yogacara) and Tathagatagarbha traditions. Bodhidharma, the first patriarch of Eastern Chan, valued it as a core teaching, distinct from other Mahayana sutras in its approach to consciousness and reality.

Main Content

The Sutra of the Descent into Lanka presents a profound dialogue between Buddha Shakyamuni and the bodhisattva Mahamati. Rather than expounding the Dharma from above, the Buddha guides the disciple to explore the perfect nature of mind (citta-matra).

The scripture gathers essential teachings. First is the doctrine of Mind-Only: all phenomena of the external world are images of consciousness. There is no absolute distinction between perceptual appearance (jnapti) and cognition, because all arise from the four layers of consciousness (alaya-vijnana, mano-vijnana, and so forth). Second is the concept of buddha-nature: every sentient being contains the nature of the Buddha, or tathagatagarbha, and need only purify the coverings of affliction.

Third, the scripture highlights the meaning of the “inexpressibility” (abhilapyata, that which cannot be spoken) of absolute truth. Language is only a skillful instrument and can never grasp ultimate reality. Therefore, genuine practice does not cling to words and letters, but goes beyond all concepts and turns toward direct realization.
