Self-realization means to know truth through yourself, and not through others. By seeking God first, through Self-realization, all things-strength, power, prosperity, wisdom, health, and immortality-will be added unto you.
Paramahansa YoganandaWhat you are is much greater than anything or anyone else you have ever yearned for. God is manifest in you in a way that He is not manifest in any other human being. Your face is unlike anyone else's, your soul is unlike anyone else's, you are sufficient unto yourself; for within your soul lies the greatest treasure of all - God.
Paramahansa YoganandaAn adept of Kriya Yoga conquers death by taking the soul beyond identification with the physical body, consciously and at will; and then returning to the consciousness of the mortal form again. By this process, he experiences the body as merely the material dwelling place of the soul. He can remain therein as long as he wants; and after that body has fulfilled its usefulness, he can quit it at will without suffering physical pain or mental pain due to attachment, and enter his omnipresent home in God.
