The Lankavatara Sutra

The Lankavatara Sutra is a central scripture of the Yogacara, or 'mind-only', school of Mahayana Buddhism, and a root text of the Chan and Zen traditions that drew deeply upon it. Composed in India in the early centuries of the common era, it takes the form of teachings delivered in answer to questions, ranging widely across the nature of perception and consciousness.

Its governing teaching is that the world as experienced is a projection of consciousness, that the distinctions and objects taken to stand outside the mind are appearances arising within it. Bondage consists in mistaking these projections for an independent reality, while liberation is described as a profound reorientation, a turning-about in the deepest seat of awareness.

This explicit framing of experience as mind-made gives the text a singular place in any genealogy of the idea that consciousness shapes reality. By locating both delusion and freedom within awareness itself, it makes the transformation of the mind, rather than the management of external conditions, the decisive event of the spiritual path, and supplied later Zen with one of its philosophical foundations.
