This book is rooted in the need to delve deeper into the historical events that led the Soka Gakkai to emancipate itself from the Nichiren Shoshu priesthood and what its intentions are as a lay religious association that concretely promotes peace, culture, and education worldwide. The first part of the volume offers an overview of the history of Buddhism, Nichiren Shoshu, and its patriarchs up to the present day, with particular regard to the narration of the events that recently led to the separation. The second part, on the other hand, deals with doctrinal aspects, specifically: the Gohonzon as an object of worship for the happiness of all humanity; the Gongyo ceremony, the meaning of daily practice; the Writings of Nichiren Daishonin, their composition and translations. The topics covered, also developed based on sources external to the Soka Gakkai, aim to make this text a valuable consultation tool not only for those who wish to have an exhaustive overview of the events with Nichiren Shoshu, but also for those who need to find philosophical-religious information.
