In plain words
The poet, of Kaṇṭam: Our Puruṣōttama has for his dwelling places Mathurā in the north, Śālagrāma, Vaikuṇṭha, Dvārakā, Ayōdhyā and spacious Badarī: his seat is the eminent city called Kaṇṭam, on the Gaṅgā, which rushes down so fiercely that great mountains [such as Mandara] shake and the earth splits and caves in, rises over the treetops and batters down the trees on its banks, and stirs up even the sea.
