I mean life-to-life rebirth, not the moment-to-moment interpretation.
Then what do you mean by "life-to-life rebirth"? "Rebirth" itself has to be defined. Life itself has to be defined. Just using the one word, "re-birth," opens it up to interpretation. Words mean different things in different languages, in different times, in different places. Do you mean "Re-incarnation"? If so, then what re-incarnates? Perhaps Buddha said what he said so that the listener did not have pre-conceived ideas of what he meant, that when he spoke of re-birth he wasn't talking about re-incarnation since using that word would close the listener's mind to what he was saying.
Buddhist Studies: Rebirth
I see it as an intriguing possibility, but I don't hold it as a belief, and it doesn't seem relevant to my daily practice.
Whether you believe in it or not may not matter if in actuality it exists. Whether one believes in Karma may not matter if it actually exists. In both there is a sense of helplessness, that one is, but one didn't have a choice. Life goes on and the body and mind want to think that it is immortal, that it will live forever. We say that Life has a drive to produce off-spring that will keep Life living, that there is a biological drive to re-produce a species, that we recognize our own immortality through the continuation of our genes. If the body has this inherent propensity, an unconscious need, to reproduce, then why can't there be a parallel in Consciousness? And what if Consciousness is part and parcel of Life?
Then Buddhist rebirth is not re-incarnation, if what the listener assumes re-incarnates is the body and the mind and the ego that one identifies with (and such identification can only happen at-the-moment one thinks about it), that one acknowledges one is. Then, to make it clear to the listener that it is not a soul that one thinks ego-body-mind is, he could have termed it 'rebirth,' to go beyond the idea that the soul is what one thinks reborns (gets re-born). Just using the word "soul" would have created assumption in the listener. The listener would have had pre-conceived ideas what re-incarnates. How then to speak words which would not produce preconceptions? He could have used the word re-birth. But then that asks the question as to what gets re-born and why Karma should now be a master to that being. If our bodies, which shape what we will be, is governed by our immediate genes inherited from our parents, and if we are also a product of all past generations modifying our genes to be inherited by successive progenies, why can't there also be a Consciousness template that gets propagated? If we can inherit ill-health, diseases, height, weight, eye colour, hair coulour, flowing hair or baldness, etc., and knowing that how we think is the sum total of our experience from the time our egos started to form, then couldn't our consciousness also be a product of Consciousness itself?, a mirror image of Consciousness? Then it is our identification with the body-mind-ego that dies, the mirror image dies, but Consciousness, like Life, continues, and in a new life form it will then identify it consciousness as a mirror image of Consciousness, just as our life is a mirror image of Life. Believing in a Life force is therefore moot - it doesn't matter whether you believe in it or not. Believing in Rebirth is moot - it doesn't matter whether you believe in it or not. Believing in beliefs is moot - it doesn't matter where you believe in it or not. Believing in reincarnation is moot - it doesn't matter whether you believe in it or not. Believing in Karma is moot - it doesn't matter whether you believe in it or not. There is a difference between Ignorance and Innocence, though.
