Seven rivers flow for Varuna, the son of waters and full of maruts. For the sake of Indra located in jhlok, human beings perform yagya etc. Those yajnakarmas are the abode of the union of gods and human beings and the sky and the earth become the opulence of these gods and human beings. The sky and the earth strive for these gods and human beings and nourish them with food, water etc. (2)
