The eternal time factor has no beginning and no end. It is the representative of the Supreme Personality of Godhead, the maker of the criminal world. It brings about the end of the phenomenal world, it carries on the work of creation by bringing one individual into existence from another, and likewise it dissolves the universe by destroying even the lord of death, Yamarāja.
