The Vedas enjoin, sarvam khalv idam brahma: everything is the energy of the Supreme Personality of Godhead, the Supreme Brahman or Param Brahman. Parasya brahmanah saktis tathedam akhilam jagat: everything is a manifestation of the energy of the Supreme Brahman. Since the energy and energetic are identical, actually everything is Krsna, Param Brahman. Bhagavad-gita (9.4) confirms this:

maya tatam idam sarvam
jagad avyakta-murtina
mat-sthani sarva-bhutani
na caham tesv avasthitah

"By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them."

Krsna is spread throughout the whole universe in His impersonal form. Since everything is a manifestation of the Lord's energy, the Lord can manifest Himself through any energy. In this age, the Lord is manifest through wood as Lord Jagannatha, and He is manifest through water as the River Ganges. Therefore Sri Caitanya Mahaprabhu ordered the two brothers-Sarvabhauma Bhattacarya and Vidya-vacaspati-to worship Lord Jagannatha and the River Ganges.
