In this short essay the author explains how the practice of mudita — sympathetic or unselfish joy — can be a potent force for eradicating jealousy, envy, and all manifestations of craving. (From the anthology: Mudita: The Buddha's Teaching on Unselfish Joy, four essays by Nyanaponika Thera, Natasha Jackson, C.F. Knight, and L.R. Oates.)
