"Sometimes people say to me 'These states that you're talking about, can't they be achieved without drugs?' And my answer to that is, 'My God, who would want to?' What would be proved by achieving these things without drugs? If the things I'm talking about began to happen to me without drugs I would be very very concerned and alarmed. And also I think there is something to be said for admitting that we cannot do it alone. That if you want this spiritual insight, if you want the Gaian matrix to welcome you, then humble yourself to the point of making a deal with a plant. That's the key."
