In plain words
The poet, of the people of the world: When Yama and Mudgala [a sinner brought before him] talked together and those who were in hell heard them, hell itself became heaven: such are the names the Perfect One has. Precious men will not say ‘His town is Araṅgam’; forgetting his names, they fall into worldly cares and are caught in sorrow, and for that alone I grieve.
