sargah pravartate tavat
paurvaparyena nityasah
mahan guna-visargarthah
sthity-anto yavad iksanam
Translation:
As long as the Supreme Personality of Godhead continues to glance upon nature, the material world continues to exist, perpetually manifesting through procreation the great and variegated flow of universal creation.
Purport:
Although the mahat-tattva, impelled by the force of time, is the ingredient cause of this world, it is clearly explained here that the Supreme Lord is personally the only ultimate cause of all that exists. Time and nature are powerless to act without the glance of the Personality of Godhead. He creates unlimited material variety for the sense gratification of the conditioned souls, who try to enjoy life as the children of particular parents and as the parents of particular children, throughout the 8,400,000 species of life.
