All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind. - Swami Vivekananda

It is the greatest manifestation of power to be calm. It is easy to be active. Let the reins go, and the horses will run away with you. Anyone can do that, but he who can stop the plunging horses is the strong man.

The cheerful mind perseveres and the strong mind hews its way through a thousand difficulties.

The Buddhists or the Jains do not depend upon God; but the whole force of their religion is directed to the great central truth in every religion, to evolve a God out of man. They have not seen the Father, but they have seen the Son. And he that hath seen the Son hath seen the Father also.
