Thank you Lal:
‘at the dying moment, a Sotapanna WILL NOT grasp (upadana) a birth in the apayas’ and that would be the very ‘suitable condition’ for such kamma vipaka to NOT materialize.
My difficulty was principally due to the two possible meanings of the word ‘conditions’ : one, in the sense of circumstances or situations or options around oneself that may be of consequence one way or another depending on one’s choice of and response to them (on condition that, provided that),and 2)the other, in the sense of one’s state of mind independent of that( one’s state of mind BEING the condition) In fact it is the second. If it were the first, then the question WOULD arise: WHAT TO DO so as NOT to grasp that bhava? – the condition being that if one does this or that then that bhava will not be grasped; if not, it will. I hope I have been clear (I have a feeling I have not)
Now, ‘Any other kamma vipaka CAN be overcome by attaining a magga phala (at least the Sotapanna stage)’ -which addresses my question itself. So one can overcome any outcome of a kamma vipaka, any bhava, that may at that moment present itself?… human,deva,rupa, arupa?
Thank you once again,
I hope your answer is relevant to others as well.
