[14] Bhikkhus, and which are the taints (āsava) to be abandoned by using (paṭisevanā)? Here, bhikkhus, a bhikkhu, reflecting wisely (paṭisaṅkhā yoniso), uses the robe only for warding off cold, for warding off heat, for warding off the touch of gadflies, mosquitoes, wind, sun, and creeping creatures, and only for the purpose of covering the private parts.
Reflecting wisely, he uses almsfood neither for amusement, nor for intoxication, nor for adornment, nor for beautification, but only for the endurance and maintenance of this body, for the ending of affliction, for the support of the holy life (brahmacariya), thinking: 'Thus I shall terminate the old feeling (vedanā) and shall not arouse a new feeling, and there will be for me sustenance, blamelessness, and a comfortable abiding.'
Reflecting wisely, he uses the lodging only for warding off cold, for warding off heat, for warding off the touch of gadflies, mosquitoes, wind, sun, and creeping creatures, only for dispelling the perils of the climate and for the purpose of delighting in seclusion.
Reflecting wisely, he uses the requisite of medicines as supports for the sick only for warding off arisen afflicting feelings and for the utmost freedom from affliction.
Bhikkhus, whereas taints, distressing and feverish, might arise in one not using [these requisites thus], for one using them thus, those taints, distressing and feverish, do not come to be. These, bhikkhus, are called the taints to be abandoned by using.
