That intense faith in another world, that intense hatred for this world, that intense power of renunciation, that intense faith in God, that intense faith in the immortal soul, is in you. I challenge anyone to give it up. You cannot. You may try to impose upon me by becoming materialists, by talking materialism for a few months, but I know what you are; if I take you by the hand, back you come as good theists as ever were born. How can you change your nature?
Swami VivekanandaAnything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences
Swami VivekanandaSay to your own minds, "I am He, I am He". Let it ring day and night in your minds like a song, and at the point of death declare : "I am He". That is truth; the infinite strength of the world is yours.
Swami VivekanandaFaith, faith, faith in ourselves, faith, faith in God, this is the secret of greatness.If you have faith in all the three hundred and thirty millions of your mythological Gods, and in all the Gods which foreigners have now and again introduced into your midst, and still have no faith in yourselves, there is no salvation for you.
Swami Vivekananda
