Let me make the link to this other topic and suggest we try as well to address the questions:
Is it possible to trace a parallel between Tibetan Buddhism’s concept of tulku and any of the aforementioned pre-anagami attainments?
Do the tulku identification / recognition methodologies shed any light on how one may know whether or not the current/present birth follows or succeeds one of those attainments? Or, how could one identify a child born in that condition?
Do EBTs indicate someone in a pre-anagami status could be able to self-recognise the attainment preceding the current birth?
