In plain words
The poet, of Tirumāliruñcōlai: The hill where he goes to dwell, who accepted the service of the one, unique elephant [Gajēndra] at the pool and took the life of Kaṃsa's one elephant [Kuvalayāpīḍa], is cool Māliruñcōlai, where, when a dark tusker's mate leaves him and runs off in a lovers' quarrel, he swears a solemn oath on the sea-coloured one, and she turns back.
