The 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 VivekanandaHe is an atheist who does not believe in himself. The old religions said that he was an atheist who did not believe in God. The new religion says that he is an atheist who does not believe in himself.
Swami VivekanandaBooks suggest the inner light and the method of bringing that out, but we can only understand them when we have earned the knowledge ourselves. When the inner light has flashed for you, let the books go, and look only within. You have in you all and a thousand times more than is in all the books. Never lose faith in yourself, you can do anything in this universe. Never weaken, all power is yours.
Swami VivekanandaNever think there is anything impossible for the soul. It is the greatest heresy to think so. If there is sin, this is the only sin; to say that you are weak, or others are weak.
Swami Vivekananda
