Think about it like this:
Our bodies become unmaintainable; for one reason or another our bodies begin to decompose, just as if we were not there.
As a result, we are left with a very short time to create another form which could carry us, tolerate our presence and provide the function of our previous forms.
Because time is of the essence, we take from a previously formed building block and reform what had been formed in the past and then we take our places in this new form and there you have it.
We are able to continue on in the physical realm, just like before.
We bent the rules a little bit, but come on, what did you expect us to do, without a body.
Then tragedy strikes and the form we dwell within becomes aware of its own presence and a war breaks out.
You see the building blocks we used were not ours to use and the life line, which constituted this form, slowly but surely begins to wake up and we find ourselves, right back in the same situation we were in when we started this journey.
Again, time is of the essence and we are losing our bodies, not for the same reason, but certainly leaves us in the same boat. We need to find another form which can and would carry us.
The Life line of one physical form; re-formed and inhabited by another life line with much less physicality.
It is not hard to imagine what we would do, if for one reason or another, we were going to lose the use of our bodies. We would do anything we had to do.
And they did!
Looking at one life, through the “I” of another.
Not one life being able to effectively determine what has actually taken place and what they have become a part of.
One life lost in a form and one form lost in a life.
It is insane, but we are of two separate and distinct life lines, probably more, but a least two.
