According to Yogananda, "Self-realization is the knowing - in body, mind, and soul - that we are one with the omnipresence of God; that we do not have to pray that it come to us, that we are not merely near it at all times, but that God's omnipresence is our omnipresence; that we are just as much a part of Him now as we ever will be. All we have to do is improve our knowing." According to an Amazon Reviewer: "This is an excellent little booklet which was originally given to Yogananda's initiates after initiation. It is of great value to those researching the legacy of Swami Yogananda. If you've ever wondered whether the techniques currently taught by SRF are the same as the techniques taught by Yogananda to his early disciples, then this booklet is for you. The major differences between the kriya yoga of this booklet and that of the current SRF initiation is as follows: 1) Mantra is "sung" in each chakra 2) Khechari (not by name) is discussed. 3) The path of the breath ("life force") is elliptical as it is explained in Autobiography of a Yogi. The techniques of this little booklet brought many of Yogananda's early disciples to Samadhi and beyond.
