Autobiography of a Yogi is an absorbing account of a singular search for Truth, interwoven with scientific explaniations of the subtle but definite laws by which yogis perform miracles and attain self-mastery.

As an authoritative introduction to the science of Yoga, Autobiography of a Yogi has become a classic in its field, revealing the scientific foundation underlying the great religious paths of both East and West.
