Go and preach to all, 'Arise, awake, sleep no more: within each of you there is the power to remove all wants and all miseries. Believe this, and that power will be manifested.
Swami VivekanandaEverything progresses in waves. The march of civilization, the progression of worlds, is in waves. All human activities likewise progress in waves - art, literature, science, religion.
Swami VivekanandaA perfect life is a contradiction in terms. Life itself is a state of continuous struggle between ourselves and everything outside. Every moment we are fighting actually with external nature, and if we are defeated, our life has to go. It is, for instance, a continuous struggle for food and air. If food or air fails, we die. Life is not a simple and smoothly flowing thing, but it is a compound effect. This complex struggle between something inside and the external world is what we call life. So it is clear that when this struggle ceases, there will be an end of life.
