Question: Does the Mind-that-is-All make substance? If not, because there can be no substance, does the Mind make a kind of a movie type reality in which all operates perfectly as if there were substance and its laws?
Response: You are making a number of assumptions here, but you seem to be pointing in the right direction. I will assume that what you mean by “Mind-that-is-All” (which is not how I would characterize Mind), is what I refer to as “Mind” in The Grand Delusion. So, I assume you are asking, “Does Mind make substance?” It does not, but not because “there can be no substance.” Strictly speaking, Mind doesn’t make a movie-like reality, either. It doesn’t make anything. As Huang Po put it, “There is only the One Mind and not a particle of anything else on which to lay hold….”
Question: Does living out of Reality—and also living in a world that encompasses the laws of physics (e.g., if I drop a raw egg from 3 feet up, it’ll break)—make a person kind of schizophrenic?
Response: Not if you just see. At that time, you might notice that these are not two different realities, ultimately. See page vii.
Question: You say "Reality is Illusion.” Is Reality the constant coming and going of seemingly separate things? What makes Reality different from the illusory nature of this seemingly concrete, conceptual world?
Response to Q1: Reality is the appearance of constant coming and going of seemingly separate things.
Response to Q2: Can’t rightly say It is different. Can’t really say It isn’t, either.
