He oppressed all those living on earth by extracting Uliyam from them. He subdued all the earthly kings and made them pay tributes to him. Suffering under his oppression, Thevarkal sought the help of Mayon, who for the purpose of destroying him, took birth as Raman.
In his death-bed Ravanan was called to repent, which he neglected by saying: "Only with the help of my brother were you able to destroy me". With this episode of killing Ravanan, Thretha yukam came to an end.
