I've recently finished reading his book "Emergentism: A Religion of Complexity for the Metamodern World". I think it's worth time reading it; it's a well balanced book.

Brendan proposes a philosophical perspective that seems to be compatible with both a (certain kind of) materialistic-atheistic worldview and a (kind of) traditional Eastern nondual perspective on God consciousness, through the lens of complexity science and other stuff.

The God consciousness is a naturalistic emergent phenomenon of matter (but not just the brain) in his perspective rather than something supernatural.

Compared to Non-Reductionist Philosophy (by David Long) Brendan is more balanced when it comes to the significance of certain altered states of consciousness as well IMO.
