Udharain Ant Na Hoi Nibahu, KalNemi Jimi Ravan Rahu
As we understand it (It is not the translation but our understanding about the chaupai) :-
Due to Malefic touch, your deed can not be identified as good one, so success is also doubtful. Just like the Ravan, who won the Death itself, but due to his wrong mission, he got his end. Lord says "Be with Holy things, do good deeds, and leave this work."
