suryo ’gnir brahmana gavo
 vaisnavah kham maruj jalam
bhur atma sarva-bhutani
 bhadra puja-padani me

O saintly Uddhava, please know that you may worship Me in the sun, fire, brahmanas, cows, Vaisnavas, sky, wind, water, earth, individual soul and all living entities.
 
Purport: 
 
Unless one understands that Lord Krsna is all-pervading and that everything is resting within the Lord, one’s Krsna consciousness is third class and materialistic. It is clearly stated in all Vedic literatures that the Supreme Absolute Truth is the source of everything. Everything is within Him, and He is within everything. To avoid a materialistic conception of Lord Krsna, one should not think that the Lord exists only in a particular time and place. Rather, one should understand that He exists at all times and in all places and that one may search for and find Lord Krsna within all things. The word puja-padani indicates that Lord Krsna is all-pervading, but this does not mean that all things are Lord Krsna. Lord Krsna speaks this verse to clarify His supremacy as the all-pervading Personality of Godhead and to show the path of complete self-realization.
