When, for example, the body ages and dies, if there is identification or clinging, there is the mistaken concept of "I am" ageing and dying (same for other khandas)
"There is the case where an uninstructed, run-of-the-mill person — who has no regard for noble ones, is not well-versed or disciplined in their Dhamma; who has no regard for men of integrity, is not well-versed or disciplined in their Dhamma — assumes form (the body) to be the self, or the self as possessing form, or form as in the self, or the self as in form. He is seized with the idea that 'I am form' or 'Form is mine.' As he is seized with these ideas, his form changes & alters, and he falls into sorrow, lamentation, pain, distress, & despair over its change & alteration.
The Buddhas khandas "aged" and "died" but "he" had attained the deathless, through non-identification (or Anatta) there is no ageing and dying, no sadness or grief since there is no longer the concept "I am this ..."
'He has been stilled where the currents of construing do not flow. And when the currents of construing do not flow, he is said to be a sage at peace.' Thus was it said. With reference to what was it said? 'I am' is a construing. 'I am this' is a construing. 'I shall be' is a construing. 'I shall not be'... 'I shall be possessed of form'... 'I shall not be possessed of form'... 'I shall be percipient'... 'I shall not be percipient'... 'I shall be neither percipient nor non-percipient' is a construing. Construing is a disease, construing is a cancer, construing is an arrow. By going beyond all construing, he is said to be a sage at peace.
"Furthermore, a sage at peace is not born, does not age, does not die, is unagitated, and is free from longing. He has nothing whereby he would be born. Not being born, will he age? Not aging, will he die? Not dying, will he be agitated? Not being agitated, for what will he long? It was in reference to this that it was said, 'He has been stilled where the currents of construing do not flow. And when the currents of construing do not flow, he is said to be a sage at peace.
Birth ageing and death are for "those" who cling to khandas
There is no justification for limiting "birth" in this passage as having only some sort of metaphorical meaning only, especially given the Buddha's own description of his awakening involves the recollection of past lives in a way that does not neatly allow for some sort of attempt to squeeze it into a metaphorical reading.
Recollection of past abodes, but even if it was past lives this just proves a point i made earlier, that if the Buddha did see past "lives", it was during his actual enlightenment. His entire motivation and view before that was an acknowledgement of what is "There is Dukkha". It wasnt "I will be reborn and so exp. Dukkha".
If people say that one must have rebirth view in order to start and practice the NEFP then they must conclude that the Buddha himself had wrong view throughout his search since he didnt start with the view "I will be reborn and suffer" since he had no knowledge of this until his nibbana (if you take it to mean he seen past lives)
