Shāntideva’s guide to the training of a Bodhisattva is one of the most important and beloved texts in the Tibetan tradition. The ninth chapter, however, dealing with Madhyamaka, the Middle Way, the most profound wisdom view of Mahayana Buddhism, has always posed unique challenges to readers. This commentary by the great scholar Mipham Rinpoche presents in quite straightforward terms Shantideva’s exposition of emptiness, the essential foundation of all Buddhist doctrine, demonstrating that it is not only compatible with, but in fact crucial to, the correct understanding of other important Buddhist teachings such as karma, rebirth, and the practice of compassion. Mipham interprets Shāntideva according to the view of the Nyingma school, which in some respects was at variance with the religiously and politically dominant interpretation of the text in Tibet at that time. As a result, his commentary stirred up a furious debate. With the addition of a critique of Mipham Rinpoche’s view by a prominent scholar of the time, along with Mipham’s response, that debate is beautifully captured in this volume.
