John Mack explored alien encounter experiences deeply, revealing a world of meaning and power that can revolutionize our understanding of who we are and our place in the cosmos. Dr. Mack suggests that such experiences reveal to us a universe which is filled with intelligence and life, though this may not always take the densely embodied form with which we are most familiar.

This book brings us to the edge of material reality and beyond, shattering the boundary that has separated matter and spirit and scientific or spiritual ways of knowing.

Dr. Mack asks us to move beyond the largely useless debate about whether UFOs or abductions are real in a purely material sense. He shows us the limited way that we have used ourselves in learning about the cosmos, and challenges the limitations of traditional science as a way to learn about the multi-dimensional world in which we reside.
