I found this book to be a thought-provoking exploration of pure awareness and its implications for human consciousness. Metzinger's approach is both philosophical and empirical, drawing on a wide range of sources to provide a nuanced understanding of MPE. The book raises many important questions about the nature of self, the role of consciousness in the universe, and the ethical challenges of mind-altering technologies.

I was particularly interested in Metzinger's discussion of the "contraction principle," which describes how the subpersonal property of phenomenality is misrepresented by the brain as the personal property of selfhood. I also found his concept of "epistemic openness" to be helpful in understanding the experience of pure awareness.

Overall, I believe that this book makes a valuable contribution to our understanding of consciousness. It is a must-read for anyone interested in the philosophy of mind, contemplative practices, or the future of artificial intelligence.
