It's my belief that one of the unconscious reasons which underlies the odd attitude of the establishment toward hallucinogens is the fact that they bring the mystery to the surface as an individual experience. In other words, you do not understand the psychedelic experience by getting a report from Time magazine or even the Economist. You only understand the psychedelic experience by having it.
Terence McKennaThis is the key. If you get into deep water with these substances, this is true of psilocybin as well, you don't want to clench, you don't want to assume the fetal position and stop breathing. You want to sit up straight and breathe, and sing, and sing it back, and it will step back. You can take control of your situation ... most of the time.
