This book aims to point out the universality and unity of religion....

In the teachings of all religions... one truth is stressed: Until man knows

himself as Spirit - the fountainhead of Bliss - he is limited by mortal concepts

and subject to the inexorable laws of nature. Knowledge of his true

being brings him eternal freedom....

If the methods here suggested are learned and earnestly practiced, you will

know yourself to be a blissful spirit and will realize God.

- Paramahansa Yogananda
