accusative singular neuter of yatindriya (adjective); also used as adverb
Analysis. yata + indriya: yata is the past participle of yatati (to restrain, control), and indriya means the sense faculties (eye, ear, nose, tongue, body, mind); the compound means 'having restrained the senses' or 'with senses controlled', a key virtue in monastic training.
Etymology. yatati is related to Sanskrit yatate (to be attentive, vigilant); indriya from Sanskrit indriya, related to Indra (the controller, lord), from the root ind- (to rule, be strong). The image is of mastery over the sense-doors rather than passivity; a meditator actively holds the senses in check.
