Translation:

The inhabitants of Krauñcadvīpa are divided into four castes, called the Puruṣas, Ṛṣabhas, Draviṇas and Devakas. Using the waters of those sanctified rivers, they worship the Supreme Personality of Godhead by offering a palmful of water at the lotus feet of Varuṇa, the demigod who has a form of water.

Purport:

Viśvanātha Cakravartī Ṭhākura says, āpomayaḥ asmayam: with joined palms the inhabitants of the various sections of Krauñcadvīpa offer the sanctified waters of the rivers to a deity made of stone or iron.
