adj
Analysis. a- (not) + gutta (guarded, past participle of guttati 'guards') + dvāra (doors); compound meaning 'doors not guarded', hence lack of restraint over the sense-gates.
Etymology. a- (negation prefix, cognate to English 'un-', Greek 'a-') + guttati from √gup 'to guard, protect' (Sanskrit gopati, gopāka 'guardian', related to English 'gaup', 'gape' in sense of watchfulness); dvāra 'door' from √dṝ 'to split, open' (Sanskrit dvār-, related to Greek 'thyra' and English 'door'); the compound reflects the Buddhist doctrine of guarding the sense-doors (indriyadvāra) to prevent unskillful mental states from arising.
