If the effect is the cause reproduced, the question is: "How is it that we find this material, dull, unintelligent universe produced from a God, who is not material, but who is eternal intelligence? How, if the cause is pure and perfect, can the effect be quite different?" What do these qualified non-dualists say? Theirs is a very peculiar theory. They say that these three existences, God, nature, and the soul, are one. God is, as it were, the Soul, and nature and souls are the body of God. Just as I have a body and I have a soul, so the whole universe and all souls are the body of God, and God is the Soul of souls. Thus, God is the material cause of the universe. The body may be changed — may be young or old, strong or weak — but that does not affect the soul at all. It is the same eternal existence, manifesting through the body. Bodies come and go, but the soul does not change. Even so the whole universe is the body of God, and in that sense it is God. But the change in the universe does not affect God. Out of this material He creates the universe, and at the end of a cycle His body becomes finer, it contracts; at the beginning of another cycle it becomes expanded again, and out of it evolve all these different worlds.
