This is a translation of the Lankavatara sutra, one of the most significant and most sophisticated of the surviving scriptures of the Sanskrit Buddhist canon, referred to as the heart of the instruction of all Buddhas. This text, here translated from the original Sanskrit, provides keys to contextualization and interpretation of different doctrines and practices of pan-Buddhism, particularly in distinguishing dogmatism from design: “This scripture has multiple meanings to guide recipients of all dispositions.”
