We shall take it for granted that there are many selves, and each self is pure and perfect; various kinds of gross and fine matter superimpose themselves on the self and make it multicoloured. Why does nature do all this? Nature is undergoing all these changes for the development 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 out before man so that he may read; and he discovers eventually that he is an omniscient and omnipotent being.
