"We don't notice them in our waking state admidst the continuous flow of visual, auditory, and other sensations for the same reason we don't see stars in the light of the sun." Anyone familiar with Hal Zina Bennett? He wrote this book back in 1987. I'm reading from the "revised and updated" version of 1994 edition. It's called "The Lens of Perception". Seems he was down in Mexico around 1964 too. Don't do internet research on him either, I'm only interested in your actual knowledge or experience with him. If you read the book back in the 80's, let me know. This book was a "underground classic". I missed it because I stopped reading during 80's. :)
