[59] Bhikkhus, therefore you should train yourselves thus: 'Our mind (citta) will be fortified in accordance with our going forth (pabbajjā), and arisen evil, unwholesome states will not remain obsessing the mind; our mind will be fortified by the perception (saññā) of impermanence; our mind will be fortified by the perception of non-self; our mind will be fortified by the perception of foulness; our mind will be fortified by the perception of danger; having known the even and the uneven of the world, our mind will be fortified by that perception; having known the coming-to-be and the passing away of the world, our mind will be fortified by that perception; having known the origin and the disappearance of the world, our mind will be fortified by that perception; our mind will be fortified by the perception of abandoning; our mind will be fortified by the perception of dispassion; our mind will be fortified by the perception of cessation.' Thus indeed, bhikkhus, should you train yourselves.
When, bhikkhus, a bhikkhu's mind is fortified in accordance with his going forth, and arisen evil, unwholesome states do not remain obsessing the mind; when his mind is fortified by the perception of impermanence; when his mind is fortified by the perception of non-self; when his mind is fortified by the perception of foulness; when his mind is fortified by the perception of danger; when, having known the even and the uneven of the world, his mind is fortified by that perception; when, having known the coming-to-be and the passing away of the world, his mind is fortified by that perception; when, having known the origin and the disappearance of the world, his mind is fortified by that perception; when his mind is fortified by the perception of abandoning; when his mind is fortified by the perception of dispassion; and when his mind is fortified by the perception of cessation — then one of two fruits may be expected for him: final knowledge (aññā) in this very life, or, if there is a residue of clinging (upādisesa), the state of non-returner.
