Therein, what is non-restraint (asaṃvara)? Here someone, having seen a form (rūpa) with the eye, is one who grasps at the sign (nimitta), one who grasps at the details (anubyañjana); since, while he dwells with the eye faculty (cakkhundriya) unrestrained, evil unwholesome phenomena (dhammā) of covetousness and grief (abhijjhā-domanassa) might flow in upon him, he does not practice for its restraint; he does not guard the eye faculty; he does not undertake restraint of the eye faculty. Having heard a sound with the ear … having smelled an odor with the nose … having tasted a flavor with the tongue … having touched a tangible (phoṭṭhabba) with the body … having cognized a mental phenomenon (dhamma) with the mind, he is one who grasps at the sign, one who grasps at the details; since, while he dwells with the mind faculty (manindriya) unrestrained, evil unwholesome phenomena of covetousness and grief might flow in upon him, he does not practice for its restraint; he does not guard the mind faculty; he does not undertake restraint of the mind faculty. This is called non-restraint.
