A Curse

Kadru gives a curse to Garud saying, the planetary life and its happiness which is in your lines will be erased forever, and your bird species will perish forever. Hence, Garud feels guilty and goes to god in despair and says, why are you smiling? Are you happy to see my mom's crying Or seeing that my brothers are struggling for every single breath? Will Garud be able to save his brother's life?
