[922] Therein, what is being unguarded as to the doors of the sense faculties (indriyesu aguttadvāratā)?
Here a certain person, having seen a form (rūpa) with the eye, is one who grasps at the sign, one who grasps at the secondary features. Since, as 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 with regard to 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 object 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 secondary features. Since, as 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 with regard to the mind faculty.
That which is the absence of guarding, the absence of protecting, the absence of watching over, the absence of restraint with regard to these six faculties — this is called being unguarded as to the doors of the sense faculties.
Therein, what is lack of moderation in eating (bhojane amattaññutā)?
Here a certain person, without reflection, without wise attention, consumes food (āhāra) for amusement, for intoxication, for adornment, for beautification. That which therein is discontent, lack of moderation, absence of reflection with regard to food — this is called lack of moderation in eating.
