The purpose of this book is to show as clearly as possible that there is an essential unity in all religions; that there is no difference in the truths inculcated by the various faiths; that there is but one method by which the world, both external and internal, has evolved; and that there is but one Goal admitted by all scriptures.
The book compares Sanskrit slokas to passages from the New Testament, especially the Book of Revelation.
He states in the introduction: “The book is divided into four sections according to the four stages in the development of knowledge.” The four sections are:
The Gospel: “…seeks to establish the fundamental truth of creation, and to describe the evolution and the involution of the world.”
The Goal: “All creatures, from the highest to the lowest in the link of creation, are found eager to realize three things – Existence, Consciousness, and Bliss.”
The Procedure: “…deals with the method of realizing the three purposes of life.”
The Revelation: “…discusses the revelations which come to those who have traveled far to realize the three ideals of life and are very near their destination.
