The purpose of life, in short, is that the only Being makes His oneness intelligible to Himself. He goes through different planes of evolution, or planes through which he arrives at different changes, in order to make clear to Himself His oneness. And as long as this purpose is not accomplished, the one and only Being has not reached His ultimate satisfaction, in which lies His divine perfection. One may ask, "Is man the only organ through which God realizes His oneness?" God realizes His oneness through His own nature. Since God is one, He always realizes His oneness through all things; through man He realizes His oneness in its fullness.
