This book is rooted in the need to want to delve into the historical events that led the Soka Gakkai to emancipate itself from the clergy of the Nichiren Shoshu and what its intentions are as a secular religious association that concretely promotes peace, culture, and education throughout the world. The first part of the volume provides an overview of the history of Buddhism, Nichiren Shoshu and its patriarchs up to the present day, with special emphasis on the narrative of the events that led to the separation in recent times. The second part, on the other hand, deals with doctrinal aspects, specifically: the Gohonzon as an object of worship for the happiness of all mankind; the Gongyo ceremony; the significance of daily practice; and Nichiren Daishonin's Writings, writing and translations. The topics covered, also developed on the basis of sources outside the Soka Gakkai, aim to make this text an agile reference tool not only for those who wish to have a comprehensive overview of the events with the Nichiren Shoshu, but also for those who need to find philosophical-religious information.
