Kotobito Ninpoden English Version 2　 178 pages, A5 size　　 This book is a compilation of secret teachings passed down orally from Hatsumi Sōke of the Bujinkan. The protagonist (the author), who grew up under parental abuse and carried its aftereffects with her (depression, anorexia, insomnia, etc.), joined the Bujinkan and profoundly changed her life through her encounters with Hatsumi Sōke. This is because when the heart changes, one’s way of living also changes. The teachings, which can be described as the crystallization of ancestral wisdom passed down in the Bujinkan, were handed down from Takamatsu-sensei to Hatsumi Sōke, and now, from Hatsumi Sōke to the next generation. Through this book, you will feel the heartfelt desire of Hatsumi Sōke to guide his students and his wish for their lives to become better. This book is packed with the candid side of Hatsumi Sōke that he usually showed only to his students in the dōjō and which few people have experienced directly. It is not about the "techniques" of "martial arts for survival" but rather a volume full of the core "teachings." It is full of the secrets regarding "ways of living" that are not taught in schools. Even for those who have no connection to martial arts but find life difficult or painful, this book is a must-read. It aims to help readers grasp "the art of survival".
