One of the many Buddhist masters who have written profoundly and with clarity about the wellsprings of the Buddhist traditions is Shantideva, a seventh-century Buddhist scholar who taught at Nalanda, one of the great monastic universities of ancient India. Shantideva's Bodhicharyavatara, one of the foundational texts of Tibetan Buddhism, deeply influenced the Dalai Lama, who once remarked that his own understanding of the bodhisattva path is based entirely upon Shantideva's text. Bodhisattvas are beings who renounce nirvana and vow to work for the welfare of all beings. The Bodhicharyavatara, which means "An Entry Into the Activities of Enlightenment," is an outline of the path that bodhisattvas should follow as they seek to teach others the path to nirvana. Thus, this collection contains meditation exercises and moral instruction for bodhisattvas to practice as they engage in their work. Shantideva's work is required reading for an understanding of Tibetan Buddhism, and the clarity and crispness of this new translation make it an accessible way into the world of Tibetan Buddhism.
