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 VivekanandaLet 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 VivekanandaSomething cannot be made out of nothing. Nor can something be made to go back to nothing.
Swami VivekanandaEvery human being has the right to ask the reason, why, and to have his question answered by himself, if he only takes the trouble.
Swami Vivekananda
