There is but one soul throughout the universe, all is but one existence - "Thou art in the woman, thou in the man, thou in the young man walking in the pride of youth, thou in the old man tottering on his stick - thou art All - in all, in everything, and I am thee, because I am made from thee."
Swami VivekanandaWe must approach religion with reverence and with love, and our heart will stand up and say, this is truth, and this is untruth.
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 Vivekananda
