In plain words
The poet, of Vēṅkaṭam: Vēṅkaṭam, where an elephant lifts its trunk and charges to gore a cloud it takes for a rival elephant, and a yāḷi, whose trunk snaps gleaming tusks, kills it so that it falls trumpeting, and stands there roaring: that is the hill of the Lord who long ago took a young calf [a demon] and flung it at the wood-apple [another demon].
