Let us realise [that] we are the infinite power. Who put a limit to the power of mind? Let us realise we are all mind. Every drop has the whole of the ocean in it. That is the mind of man. The Indian mind reflects upon these [powers and potentialities] and wants to bring [them] all out. For himself he doesn't care what happens. It will take a great length of time [to reach perfection]. If it takes fifty thousand years, what of that!
Swami VivekanandaTo succeed, you must have tremendous perserverance... tremendous will. "I will drink the ocean", says the perservering soul; at my will mountains will crumble. Have that sort of energy, that sort of will; work hard, and you will reach the goal.
Swami Vivekananda
