Thought ceases in meditation; even the mind's elements are quite quiet. Blood circulation stops. His breath stops, but he is not dead.
Swami VivekanandaWhen we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were but we shall understand the whole thing. The same phenomena will remain but with a new meaning.
Swami VivekanandaHow has all the knowledge in the world been gained but by the concentration of the powers of the mind? The world is ready to give up its secrets if we only know how to knock, how to give it the necessary blow. The strength and force of the blow come through concentration. There is no limit to the power of the human mind. The more concentrated it is, the more power is brought to bear on one point; that is the secret.
Swami Vivekananda
