What evolution looks like when it's applied to the conscious mind
Format: Kindle
It's difficult to say what this book has meant to me over the last 30(?!) years. It is one I return to again and again, and I always get something new from it. The Strieber's commitment to living in the question and keeping it open without jumping to conclusions about where the beings originate and why they are here should be a master class for investigators in the field.
There were concepts so foreign to me when I first read this as a teen who was only there for "the alien stuff" that now resonate so deeply. Concepts beyond the question of the visitors; ruminations on spirituality, meditation, marriage that have been a guiding force in my life. I grew up surrounded by awful marriages, reading a man talk so reverently about his wife and their life together actually changed my perception of what was possible in relationships.
This book has ruined most other books by experiencers for me, because while others may certainly have interesting stories, they aren't all gifted writers of this caliber. The sincerity, confusion, fear, and ultimately bravery to confront the unknown are palpable. I can't wait to read the new introduction and dive into the mystery all over again.
