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 VivekanandaLearn to feel yourself in other bodies, to know that we are all one. Throw all other nonsense to the winds. Spit out your actions, good or bad, and never think of them again. What is done is done. Throw off superstition. Have no weakness even in the face of death. Be free.
Swami Vivekananda
