David Rabin defines psychedelics as mind-revealing states you can reach without drugs. Breathing, meditation, yoga, exercise, and touch all work. Medicines should teach you to access these states on your own, not make you dependent on them.

The word psychedelic means mind revealing and it is about a state of mind. Psychedelic is not a word that only describes drug induced experiences. The reason why that's important is because psychedelic states are achievable naturally without drugs and without medicine, and can be achieved through breathing techniques, meditation, yoga, soothing touch intimacy, physical exercise, watching a beautiful sunset or moonrise, and medicines are just one of many tools that help us to get there. The reason why this is so important to understand is because the purpose of psychedelic medicines is to facilitate and train us to learn how to access psychedelic states of mind completely naturally. If we become dependent on the medicine, we're missing the point.
