This book delves deeply into the essence of the Nembutsu, written by Kosho Otani, the 25th Monshu (Head Priest) of the Shinshu Otani-ha sect. Perhaps because of the double case, the condition is excellent, and the main body is as clean as if it were a new book. It also has a vinyl cover. The gold outer case is beautiful, and it has a sense of weight when placed on a bookshelf as a collection. It is a good book that has been read not only as a devotional book of Jodo Shinshu Buddhism but also as an introductory book to Buddhist thought and religious ethics. Recommended for those interested in Jodo Shinshu and Shinran's thought, those who want to practice the Nembutsu in their daily lives, those looking for spiritual religious books, and those who want to carefully read old Buddhist books.
