In plain words
The poet, of the Lord: The shoulders of him whose glorious couch is the coiled serpent are the ones that crawled between the joined marutu trees, pushed down the flowering kuruntam, killed the seven huge bulls to win a bride [Nappiṉṉai], strode across the seven worlds [as Trivikrama] while the hosts [of gods and demons] trembled, and spread through the eight directions.
