This book is divided into three volumes with ten sections. The writing of the book began in the latter part of 1925 and was completed in June 1927. The following explanation by the author himself on the nature of the book is quoted from an
announcement in Issue No. 3 of The Present Testimony: “This book puts particular emphasis on spiritual reality. Hence, what is covered in each volume can all be attested in experience; nothing is there as an empty word. “The most frustrating experience of believers today is that in seeking for progress on the spiritual path, they do not find the proper way. As a result, they grope in darkness, being at times high or low, lingering around the crossroads year in and year out, and having no one to consult for direction. The author of this book was such a one.
