We find the vast majority of people in every country believing that there will be a time when this world will become perfect, when there will be no disease, nor death, nor unhappiness, nor wickedness. That is a very good idea, a very good motive power to inspire and uplift the ignorant. But if we think for a moment, we shall find on the very face of it that it cannot be so. How can it be, seeing that good and evil are the obverse and reverse of the same coin? How can you have good without evil at the same time?
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 VivekanandaThe brain and muscles must develop simultaneously. Iron nerves with an intelligent brain — and the whole world is at your feet.
Swami VivekanandaThe mind is but the subtle part of the body. You must retain great strength in your mind and words.
Swami Vivekananda
