In plain words
The poet, of Araṅgam: He became the fish full of splendour, the tortoise, the boar, the lion, the dwarf, Rāma in three forms [Paraśurāma, Rāma son of Daśaratha, and Balarāma], Kaṇṇaṉ and Kalki, and makes an end of his foes: his temple is Araṅgam of the waters, where the female swan, joined with her mate, climbs onto a red lotus and swings on it, and they press close on that bed of flowers and play, bathed in the red pollen that rises.
