In plain words
The poet, of Śrīraṅgam: He who loosed his leaf-tipped arrows and destroyed the defences of Laṅkā [Rāma] is the Lord who dwells for ever in Araṅgam, on the Kāviri, which is born on the peak of the mountain [Sahya], comes down driving sandalwood before it, tears and tosses and snaps the saffron creepers, and flows on beating its banks with the saffron paste they shed.
