“In these tumultuous times of the 21st century, I hope that, for the sake of world peace, you will join me in learning from the infinite wisdom of *The Collection of Oral Teachings*. Let us strive together to gain a deeper understanding of Nichiren Buddhism, a teaching of authentic humanism and respect for life.” With these words, Master Ikeda explained his decision to undertake a series of in-depth explorations of the fundamental message of the Lotus Sutra, collected and presented in their entirety in this book.
