Acharya Prashant explains that true welfare and goodness arise only when one has no personal interest or motive in the world. He argues that as long as we have a purpose or desire related to someone, we inevitably cause them harm, either directly as an enemy or indirectly in the name of help as a friend. Real service is possible only when there is no 'taking' involved, which happens when a person is internally complete and whole. Such a person, being self-sufficient, has neither desires nor duties toward others, as duty often feels like a debt or burden. When both desire and duty vanish, true well-being or 'Kalyan' emerges.
