True religion comes not front the teaching of men or the reading of books; it is the awakening of the spirit within us, consequent upon pure and heroic action.
Swami VivekanandaIf religion and life depend upon books or upon the existence of any prophet whatsoever, then perish all religion and books! Religion is in us. No books or teachers can do more than help us to find it, and even without them we can get all truth within. You have gratitude for books and teachers without bondage to them; and worship your Guru as God, but do not obey him blindly; love him all you will, but think for yourself. No blind belief can save you, work out your own salvation. Have only one idea of God - that He is an eternal help.
Swami VivekanandaYou cannot take away one atom of matter or one foot-pound of force. You cannot add to the universe one atom of matter or one foot-pound of force. As such, evolution does not come out of zero; then, where does it come from? From previous involution.
Swami Vivekananda
