The rest is explained throughout the trilogy, but I think your question is explained adequately in the link.
I did read it. It seems that you're going to have to explain to me how he avoids either:

a) an infinite regress of extended causal systems each of which has a beginning that appears mystical from within it until we move to the next level up.
b) an extended causal system which is infinite.

If he does not avoid one of those, I wonder how he claims that that is any less mystical than the beginning of our own causal system when viewed from within it.

My point is that dismissing the mystical as the lack of a potentially complete and logical understanding is just as mystical as anything else.
