Why is nature doing all this? Nature is undergoing all these changes for the improvement of the soul; all this creation is for the benefit of the soul, so that it may be free. This immense book which we call the universe is stretched before man so that he may read, and come out, as an omniscient and omnipotent being. I must here tell you that some of our best psychologists do not believe in a personal God in the sense in which you believe in Him. The real father of our psychologists, Kapila, denies the existence of God as a Creator. His idea is that a personal God is quite unnecessary; Nature itself is sufficient to work out all that is good. What is called the “Design” theory he repudiated, and said a more childish theory was never advanced. But he admits a peculiar kind of God; he says we are all struggling to get free, and when man becomes free he can, as it were, melt away into Nature for the time being, only to come out at the beginning of the next cycle and be its ruler; come out an omniscient and omnipotent being. In that sense he can be called God; you and I and the humblest beings will be gods in different cycles. Kapila says such a God will be temporal, but an eternal God, eternally omnipotent and eternally ruler of the universe, cannot be. If there were such a God, there would be this difficulty: he must either be bound or free. A God who is perfectly free would not create; there would be no necessity. If he were bound, he would not create because he could not, he would be weak himself. So, in either case, there cannot be an omnipotent or omniscient eternal ruler. So wherever the word God is mentioned in our Scriptures, Kapila says it means those perfected souls who have become free. The _Sânkhya_ system does not believe in the unity of all souls. Vedânta believes that all individual souls are united in one cosmic Being called _Brahman_, but Kapila, the founder of the _Sânkhya_, was dualistic. His analysis of the universe so far as it goes is really marvellous. He was the father of Hindu evolutionists, and all the later philosophical systems are simply outcomes of his thought.
