The Living Force
Seems like a bit of an assumption there. How do we know that 50% of humanity isn't capable of the appropriate soul matches and it's the epigenetic influences of a particular soul that determine the level of receivership capability? A good question I like to ask myself sometimes is, "To what level is what I've written conditioned by materialist assumptions?" You can discover surprising things about your beliefs this way.
Well OK since you are interested in materialist assumptions, let's look at it that way. On any given day there are X births all of which are opportunities to be born. But let's eliminate the OP's which are what, half now? And you say how do we know that half of humanity isn't capable of providing fertile ground for a given soul. So, now we are down to a 25% chance already. And how far of a stretch is it to say that for certain types of souls half of those are just not made of the right karmic stuff to match up? (and how many types are there? we don't know but I think Gurdjieff may have alluded to such a thing) Now we are at 12.5% minimum or, getting close to a 10-1 difference.
That said, It is true I didn't define "far fewer". My basic point is that for some souls, the field is narrow, especially if it involves some kind of karma that involves specific souls. (and how can any soul know, once the veils are in place, what the hell is really going on?) So, for me, it's an open question and good luck and may the Holy Spirit be with you in making those choices. Lastly, I am saying this from experience, not materialist assumptions.
