Knowledge is inherent in man; no knowledge comes from outside; it is all inside. We say Newton discovered gravitation. Was it sitting anywhere waiting for him? It was in his own mind; the time came and he found it out. All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind. The external world is simply the suggestion, the occasion, which sets you to study your own mind.
Swami VivekanandaAlways keep the mind cheerful. Everyone will die once. Cowards suffer the pangs of death again and again, solely due to the fear in their own minds.
Swami VivekanandaPresent-day Hinduism and Buddhism were growths from the same branch. Buddhism degenerated, and Shankara lopped it off!
Swami VivekanandaWhat do you gain in heaven? You become gods, drink nectar, and get rheumatism. There is less misery there than on earth, but also less truth.
Swami VivekanandaI think the Greeks first took astrology to India and took from the Hindus the science of astronomy and carried it back with them from Europe. Because in India you will find old altars made according to a certain geometrical plan, and certain things had to be done when the stars were in certain positions, therefore I think the Greeks gave the Hindus astrology, and the Hindus gave them astronomy.
Swami Vivekananda
