Ārya Asanga’s Bodhisattvabhūmi, or The Stage of a Bodhisattva, is the Mahāyāna tradition’s most comprehensive manual on the practice and training of bodhisattvas—by the author’s own account, a compilation of the full range of instructions contained in the entire collection of Mahāyāna sutras. A classic work of the Yogācāra school, it has been cherished in Tibet by all the historical Buddhist lineages as a primary source of instruction on bodhisattva ethics, vows, and practices, as well as for its summary of the ultimate goal of the bodhisattva path—supreme enlightenment.

Despite the text’s seminal importance in the Tibetan traditions, it has remained unavailable in English except in fragments. Engle’s translation, made from the Sanskrit original with reference to the Tibetan translation and commentaries, will enable English readers to understand more fully and clearly what it means to be a bodhisattva and practitioner of the Mahāyāna tradition.
