SB 10.2.28, Purport

 

Persons who are not in real knowledge think that Brahmā is the creator, Viṣṇu the maintainer and Śiva the annihilator and that the different demigods are intended to fulfill diverse purposes. Thus they create diverse purposes and worship various demigods to have these purposes fulfilled (kāmais tais tair hṛta jñānāḥ prapadyante 'nya-devatāḥ (BG 7.20)). A devotee, however, knows that these various demigods are but different parts of the Supreme Personality of Godhead and that these parts need not be worshiped.
