In plain words
The poet, of Vēṅkaṭam: Where the rutting elephant joins its noble mate, then quarrels with her in love, wanders off, and in its anger strikes against the rocks, and in the pride of its valour sheds pearls from its white tusks: that Vēṅkaṭam is the hill of the Lord who long ago, one day, took the earth up on his tusk [as the Boar].
