Lord Krishna... proclaims Self-realization, true wisdom, as the highest branch of all human knowledge-the king of all sciences, the very essence of dharma ("religion")-for it alone permanently uproots the cause of man's threefold suffering and reveals to him his true nature of Bliss. Self-realization is yoga or "oneness" with truth-the direct perception or experience of truth by the all-knowing intuitive faculty of the soul.
Paramahansa YoganandaMeet everybody and every circumstance on the battlefield of life with the courage of a hero and the smile of a conqueror.
Paramahansa YoganandaWork for god, love god alone, and be wise with god. When an ordinary man puts the necessary rime and enthusiasm into meditation and prayer, he becomes a divine man.
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.
