God-realization is the most difficult state to reach. Let no one fool himself, nor think that someone else can "give" it to him. Whenever I fell into a state of mental stagnation, my Master could do nothing for me. But I never gave up trying to keep in tune with him by cheerfully performing whatever he asked me to do. "I have come to him for God-realization," I reasoned, "and I must listen to his advice."
Paramahansa YoganandaThe universal law of karma ... is that of action and reaction, cause and effect, sowing and reaping. In the course of natural righteousness, man, by his thoughts and actions, becomes the arbiter of his destiny.
Paramahansa YoganandaEver-new Joy is God. He is inexhaustible; as you continue your meditations during the years, He will beguile you with an infinite ingenuity. Devotees like yourself who have found the way to God never dream of exchanging Him for any other happiness; He is seductive beyond thought of competition.
Paramahansa YoganandaMind is the creator of everything. You should therefore guide it to create only good. If you cling to a certain thought with dynamic will power, it finally assumes a tangible outward form. When you are able to employ your will always for constructive purposes, you become the controller of your destiny.
Paramahansa YoganandaLord 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.
