It is the goddess Nature who causes birth and death. When the time comes for Universal Dissolution, all existent objects and qualities are withdrawn by the Supreme Soul which then exists alone like the Sun withdrawing at evening all his rays; and when the time comes for Creation. He once more creates and spreads them out like the Sun shedding his rays when morning comes. Thus the Soul, for the sake of spol, repeatedly considers himself invested with all these conditions, which are his own forms and qualities infinite in number, and agrecable to himself. It is thus that the Soul, though really above the three qualities, becomes attached to the path of acts and creates by modification nature invested with the conditions of birth and death and at once with all acts and conditions which are characterised by the three qualities of Goodness, Darkness, and Ignorance. Arrived at the path of action, the Soul considers particular acts as possessing particular characteristics and productive of particular ends.
