In plain words
The poet, to the people of the world: By his own will he kicked apart the cart-demon [Śakaṭa] with his foot, shook the serpent [Kāḷiya] till its pride was gone, seized the elephant [Kuvalayāpīḍa] and broke its tusks, drank the poison from the demoness's [Pūtanā's] breast, and broke the humps of the mighty bulls for Piṉṉai of the fine coral lips and lovely shoulders; and so, moreover, he stood revealed as the Lord of all.
