That’s interesting but it was the other half of my post that did have relevance to the OP i.e.
Can you also remember when you appeared on the scene this time around? Was it when the little tadpole wriggled into the egg and dissolved or, was it a bit later on - when your senses and nervous system became integrated? If it was before that, what was it that made you cotton-on to the fact of your existence (this time around) or, have you forgotten the details?
Can you remember being a zygote and what were your thoughts at the time? Ajahn Sujato mentioned - according to his sources - it all starts with the first thought.
I was told that what we are thinking at the time of death is important with regard to the nature of the next life. You may be the one who has this missing information that we are looking for?
What was the first thought that appeared in your mind in this life and, at what stage in the development of the foetus did this event take place?
The last thought is meant to be important in determining what kind of rebirth takes place. Rebirth would be indicated by the first thought in the next life.
In Advaita teachings they say the first thought is ‘I am’ and on the basis of this thought other thoughts can proliferate like, I am this or, I am that. In order to develop a ‘sense of self’ - I am ‘something’ having an experience - it requires the thought of self-existence. This is how Advaita teachings were explained to me.
The first indication of a return to ordinary waking consciousness after ‘deep meditation’ - when the senses are not operating - is recognition that sense-contact is taking place. Once this happens the sense of ‘I am here’ is possible.
By encompassing anothers mind with his mind an awakened being like the ‘Buddha’ may be able to perceive when the first thought arises in a new life? He does not seem to have said when this happens?
Is there a teaching in the EBT’s where the Buddha or, another fully awakened being, clearly states when the first mental formation arises in a new life?
Clearly, without this information we cannot determine when an abortion would be the termination of a sentient form of existence or, when that would not be the case?
