"A psychedelic experience is a journey to new realms of consciousness. The scope and content of the experience is limitless, but its characteristic features are the transcendence of verbal concepts, of space-time dimensions, and of the ego or identity. Such experiences of enlarged consciousness can occur in a variety of ways: sensory deprivation, yoga exercises, disciplined meditation, religious or aesthetic ecstasies, or spontaneously. Most recently they have become available to anyone through the ingestion of psychedelic drugs such as LSD, psilocybin, mescaline, DMT, etc. Of course, the drug does not produce the transcendent experience. It merely acts as a chemical key — it opens the mind, frees the nervous system of its ordinary patterns and structures."

“My advice to myself and to everyone else, particularly young people, is to turn on, tune in and drop out. By drop out, I mean to detach yourself from involvement in secular, external social games. But the dropping out has to occur internally before it can occur externally. I'm not telling kids just to quit school; I'm not telling people to quit their jobs. That is an inevitable development of the process of turning on and tuning in.”

“People use the word "natural" … What is natural to me is these botanical species which interact directly with the nervous system. What I consider artificial is four years at Harvard, and the Bible, and Saint Patrick's cathedral, and the sunday school teachings.”
