I have practiced meditation for over 20 years, and this book gives a complete explanation of the Kriya yoga meditation technique, as well as lessons on living a life of virtue and the "Rainbow Path" of right living. There are several reviews stating that this is not the Kriya technique of Self Realization Fellowship, which is true. In his book "Christ Consciousness", Mr. Paulsen writes about his time living with Yogananda. Mr Paulsen's Kriya technique has been fine-tuned through his own Divine experiences. This book is transformational and has been a great help to me personally and furthered my own spiritual growth and fulfillment.
