The body is subject to the law of growth and decay, what grows must of necessity decay.
Swami VivekanandaThe book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
Swami VivekanandaKnowledge is inherent in man; no knowledge comes from outside; it is all inside. We say Newton discovered gravitation. Was it sitting anywhere waiting for him? It was in his own mind; the time came and he found it out. All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind. The external world is simply the suggestion, the occasion, which sets you to study your own mind.
Swami VivekanandaSince everything emanates from God, he is the embodied principle in every being. Each one of us is made from God. Tat twam asi - "You are That One" who is eternally blissful, that one principle manifesting itself as this variety of Creation.
Swami Vivekananda
