Addressing questions such as What constitutes a meaningful life? and What is true happiness?, this guide to Nichiren Buddhism presents the spiritual practice as a teaching of hope that can answer these and other important questions of modern life. Buddhist teacher Daisaku Ikeda offers insights into four of Nichiren's revolutionary letters—each intended to bring out the inherent potential within each individual—and brings the message of the missives to life for a contemporary readership. Readers will not only learn about the exceptional life and times of Nichiren, they will also discover a philosophy of inner transformation that will help them find deep and lasting happiness for themselves and for others. This is the only book that offers commentaries on the writings of the 13th-century teacher Nichiren, one of the most important Japanese Buddhist teachers in the Mahayana tradition.
