[12] "Bhikkhus, forms (rūpā) of the past and future are not-self (anattā); what, then, need be said of those that are present? Seeing thus, bhikkhus, the instructed noble disciple is without concern for forms of the past, does not delight in forms of the future, and is practising for disenchantment (nibbidā) with, for dispassion (virāga) towards, and for the cessation of forms that are present.
Sounds, odours, tastes, tangibles, and mental phenomena (dhammā) of the past and future are not-self; what, then, need be said of those that are present? Seeing thus, bhikkhus, the instructed noble disciple is without concern for mental phenomena of the past, does not delight in mental phenomena of the future, and is practising for disenchantment with, for dispassion towards, and for the cessation of mental phenomena that are present."
