Don't know about birthing but have some ideas from research about dying. Have interviewed people who had been unconscious and others who were on hospice. May not be as linear as you might think. The body changes and loses function first. What seems to happen is the loss of body structure opens up doorways to transpersonal experiences, soulful maybe. People can see deceased relatives, go to a heavenly place, for example. The mind from the previously unconscious patient study seems to function even when the body is weak. Inner dialogue is possible even though thought processes theoretically should have been altered. The spirit, soul, or energy leaves the body at the time of death which has been described by family members and healthcare professionals and even photographed.
"Der Körper ist bei der Geburt und auch beim Tod nur feste Materie. Er beinhaltet Organe die es ihm ermöglichen zu leben oder bei Versagen, zu sterben. Die Seele ist das manifeste ich, das mit dem Geist zusammen arbeitet und mich so sein lässt wie ich bin. Werde ich geboren, so formt sich der Körper um meinen Geist und meine Seele. Stirbt der Körper gibt auch der Geist irgendwann auf, meine Seele jedoch gelangt in die Freiheit." Das ist meine Vorstellung.
Es gibt im Internet zahlreiche Verweise zu Nahtoderfahrungen, Vielleicht ist es sinnvoll diese zu studieren. 2016 wurde die „Aware“-Studie (AWAreness during REsuscitation) veröffentlicht.
A very interesting question. It has been my experience that life is cyclical, but what does that mean? I have worked with hospice patients whose lives are ending. I have done hypnotherapy with clients who have gone back into their mother's womb. As a baby's body is developed, its soul is already part of it. When death occurs, what remains weighs approximately 3 oz less. Given those things, I believe it is soul, mind (however undeveloped it may be), body in birth; and in death it is body, mind, and soul. However, I do not remember being born and I have not yet died so the proof will be in the experiencing. As a Christian, I know that my soul does not die; merely sleeps to be awakened when God sees fit.
I hope that helps you in your research. I am very interested in reading the finished product! Please, make it available in its entirety here on ResearchGate.
The soul (which is not of this world, can never be satisfied with the means/goods of this world); mind and body are the physical tools of this process.
