Millions upon millions of births have to be gone through by Individual Soul in the successive forms he assumes, all of which are liable to death. He who does acts in this way, which are all full of good and bad fruits, has in the three worlds to assume successive forms and to enjoy and suffer fruits corresponding therewith. It is Nature that causes good and bad acts; and it is Nature that enjoys and suffers the fruits thereof in the three worlds. Indeed, Nature follows the course of acts. The status of the intermediate beings, of humanity, and of the gods, all originate from Nature. Nature has been said to be shorn of all qualities. Her existence is proved by her acts.
