I think the view here is consistent with some kinds of mysticism, at least, as I say in the article. I'm more of a naturalistic humanist, so the view here is also consistent with that scientific explanation of the self.
All you need is a distinction between the self and everything else, and mystical monism supplies that by distinguishing between a divine consciousness and the illusions of materiality and plurality.
My main point is just that so-called sacred spaces outside the self derive from the reverence for the subjective aspects of the self (for qualia and vitality).
