Query: Well worth having.

This is a strange little book, recommended by Yogi Ramacharaka in the intro to his Bhagavad Gita as an aid to understanding its teachings. But this is not an easy book to read, consisting as it does of several hundred brief quotations from the Upanishads and a number of gurus and swamis. The selections contain many specialized terms such as THAT, the Absolute, Self, Karma, etc. without any explanation for the uninitiated. I think the book would better serve as an adjunct to the Yogi's "Lessons in Gnani Yoga" or his outstanding compendium "The Philosophies and Religions of India." Having said all this, however, the book is well worth having. The reader is rewarded with many startling and profound passages, and some that could be excellent subjects for one's personal meditations. I am glad I heeded the Master and bought his little book.
