How 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 VivekanandaIf you can get rid of your attachment to a single thing, you are on the way to liberation.
Swami VivekanandaJnana teaches that the world should be given up, but not on that account to be abandoned. To be in the world but not of it-is the true test of the sannyasin.
Swami VivekanandaThat which is nearest is least observed. The Atman is the nearest of the near, therefore the careless and the unsteady mind gets no clue to it. But the person who is alert, calm, self-restrained, and discriminating ignores the external world and, diving more and more into the inner world, realizes the glory of the Atman and becomes great.
Swami Vivekananda
