Dennis McKenna quotes:

Ayahuasca is a symbiotic ally of the human species.

All experience is a drug experience. Whether it's mediated by our own [endogenous] drugs, or whether it's mediated by substances that we ingest that are found in plants, cognition, consciousness, the working of the brain, it's all a chemically mediated process. Life itself is a drug experience.

Nobody can have your psychedelic experience for you; you just have to screw your courage up and raise the cup to your lips or smoke the pipe or whatever it is and face what's in there.

Think for yourself, and believe in yourself. Keep your skeptical antennae tuned in and in good working order at all times. We are free to develop our own hypotheses, which should be based in available evidence. When it comes to faith, have faith in yourself. And don't forget to love, laugh, be kind to each other. Don't take things so seriously, especially yourself. If the universe is a cosmic joke, remember to giggle. And remember to be astonished.

I get frustrated with people who say that a drug experience can have no spiritual validity. I'm here to tell you that all experience is a drug experience. We're all on drugs all the time, largely because we are MADE of drugs
