The Bhagavad Gita


In the beginning there was Existence alone — One only, without a second. He, the One, thought to himself: Let me be many, let me grow forth. Thus out of himself he projected the universe, and having projected out of himself the universe, he entered into every being. All that is has its self in him alone. Of all things he is the subtle essence. He is the truth. He is the Self. And that ... THAT ART THOU. (Living Religions, 77 [Chandogya Upanishad])
[Karma] means action, and also the consequences of action. Every act we make, and even every thought and every desire we have, shapes our future experiences. Our life is what we have made it. And we ourselves are shaped by what we have done: “As a man acts, so does he become. ... A man becomes pure through pure deeds, impure through impure deeds.” Not only do we reap in this life the good or evil we have sown; they also follow us after physical death, affecting our next incarnation. Ethically, this is a strong teaching, for every move has far-reaching consequences. (Living Religions, 77)
