The essential thing in religion is making the heart pure; the Kingdom of Heaven is within us, but only the pure in heart can see the King. While we think of the world, it is only the world for us; but let us come to it with the feeling that the world is God, and we shall have God.
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.
Swami VivekanandaWhat makes you weep, my friend? In you is all power. Summon up your all-powerful nature, O mighty one, and this whole universe will lie at your feet. It is the Self alone that predominates, and not matter.
Swami Vivekananda
