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 VivekanandaRenunciation - non-resistance - non-destructiveness - are the ideals to be attained through less and less worldliness, less and less resistance, less and less destructiveness. Keep the ideal in view and work towards it. None can live in the world without resistance, without destruction, without desire. The world has not come to that state yet when the ideal can be realised in society.
Swami VivekanandaYou must have an iron will, if you would cross the ocean. You must be strong enough to pierce mountains.
Swami Vivekananda
