1st person singular optative middle (or gerundive: 'should be rejoiced in'), from anumodati
Analysis. anu- (along, following) + √mud (to be joyful) — 'following in joy with', hence delighting in another's good deeds; a characteristic Buddhist practice of sharing in others' merit.
Etymology. anu- (tracking after, sympathetic alignment) + √mud (to be glad, cognate with English mood in its archaic sense of courage or state of mind). The compound captures the meditative practice of rejoicing in the virtue of others rather than envying them, especially after hearing of gifts or moral acts.
