"There has been nothing before, written in English or in any other European language, like this presentation of Yoga."
Autobiography of a Yogi is available at most bookstores, or may be ordered directly from Self-Realization Fellowship.
Self-Realization Fellowship's editions, and none others, incorporate all of Paramahansa Yogananda's wishes for the final text, including the extensive material he added after the original 1946 edition.
