The greatest sin is to think that you are weak. No one is greater: realize that you are Brahman. Nothing has power except what you give it.
Swami VivekanandaNeither numbers nor powers nor wealth nor learning nor eloquence nor anything else will prevail, but purity, living the life, in one word, anubhuti, realisation. Let there be a dozen such lion-souls in each country, lions who have broken their own bonds, who have touched the Infinite, whose whole soul is gone to Brahman, who care neither for wealth nor power nor fame, and these will be enough to shake the world.
Swami VivekanandaIf a man, day and night, thinks he is miserable, low and nothing, nothing he becomes. If you say yea, yea, "I am, I am", so shall you be.
Swami Vivekananda
