Psychedelia is art and philosophy extending beyond sound and psychotropic substances.
For some, psychedelia is a way of life, a spiritual answer to our existential questions and part of everyday 'reality'. There are too many book writers to mention here but Carlos Castaneda, Timothy Leary, Rick Strassman, Aldous Huxley, Tom Robbins, Terence McKenna and William Boroughs are perhaps the most important ones.
