In plain words
The poet, of the Lord at Kuṭantai: He of the sea-like form [Rāma], who went that day, attacked and cut down the one [Rāvaṇa] who thought to rest on the breast of the Lady [Sītā] with conch bangles on her forearms, so that his body perished, is the one of lotus-like limbs who lies in cool Kuṭantai, whose waters swell where women with long, fragrant tresses bathe.
