Cleanse Sudev of all evil thoughts? If that were a solution, wouldn't it solve pretty much everything? Cleanse all asuras of any thoughts of tyranny, cleanse Indra of any thoughts of foul play, cleanse Vishnu of any thoughts of playing tricks on asuras, and so on
Years ago, I once saw a movie about a character Doc Savage. At the end of it, the criminal in question asks whether he'll be killed. He's told that Doc Savage doesn't believe in that, and instead, subject him to an operation and intense therapy which will cure him of his evil nature. My dad remarked that there should be a limit on fantasies.
Or in the previous track itself, Shiva could have gotten rid of all of Vinayak's thoughts of opposing him, and resolved that issue that way.
