The Rosicrucian Cosmo Conception was written by Max Heindel, founder of the Rosicrucian Fellowship in 1909. The teachings contained herein are otherwise known as The Western Wisdom Teachings, and are called Mystic Christianity.

I first read this in 1969 aboard a train taking me from North Bay, Ontario to Vancouver, British Columbia.
 In this book you may find answers which you  have been seeking all your life, and even answers to questions you have never asked. A story is told of an individual who had this book on his shelf for twenty years, and when he found it, found it to be the answer to a life long search.
