According to Osho, the highest service to others is your own inner elevation through sadhana. When your 'height' matures, its silent rays naturally uplift those around you; no reforming or molding is needed. Attempts to 'do good' often mask ego and violence. Cultivate being yourself; your awakened presence becomes a non-coercive blessing for the whole.
If you light your own lamp, people nearby can see better too—without you pushing them.
