This is the first English translation of the authoritative commentary of Shantideva's classic The Way of the Bodhisattva that has been studied deeply in the Tibetan language by practitioners and scholars alike for a century. The Way of the Bodhisattva, renowned for its inspirational message and for the lyric beauty of its verses, is the subject of many books, including Pema Chodron's No Time to Lose and the Dalai Lama's A Flash of Lightning in the Dark of Night.
