Translation:
O supreme creator, it is You who generate this universe, composed of the variegated arrangement of the material modes, and in the process You manifest various kinds of personalities and species, varieties of sensory and physical strength, and varieties of mothers and fathers with variegated mentalities and forms.
Purport:
Commenting on this verse, Srila Madhvacarya has quoted the Narada Purana as follows: “From Hiranyagarbha, Brahma, comes the second creation of this universe, but the universe is primarily created by Visnu Himself. Visnu is thus the primary creator, and four-headed Brahma is merely the secondary creator.”
