O King, this time factor enhances the sattva-guna. Thus although the Supreme Lord is the controller, He favors the demigods, who are mostly situated in sattva-guna. Then the demons, who are influenced by tamo-guna, are annihilated. The Supreme Lord induces the time factor to act in different ways, but He is never partial. Rather, His activities are glorious, therefore He is called Urusrava.
