This concise, readily understandable book is designed as a guide to one of the supreme scriptures of Mahayana Buddhism: the Threefold Lotus Sutra. The first publication of the complete sutra in English (Kosei, 1975) was widely acclaimed, and an ever-growing audience has been created for what is certainly among the greatest of the world's religious documents. Like the Bible and the Koran, however, the Threefold Lotus Sutra requires explanation by a gifted teacher, and it is for this reason that Niwano has written this guide. Giving careful consideration to the relationships among the thirty-two chapters of the sutra, he not only outlines the contents but also explains the major points.
