Arya Asanga's Bodhisattvabhumi, or The Stage of a Bodhisattva, is the Mahayana 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 Mahayana sutras. A classic work of the Yogacara 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.
