"I always trusted what happened on acid. Everything that happens to you on acid is real. Everything you see is real, everything you experience is real, everything you think about is real. The thing about it is, that a lot of the stuff you see is not stuff you see when you're straight, because when you're straight you're limited. The acid removes the "filters" and lets the noise through. That "noise" is as real a part of the universe as the other part that you do allow to pass through, it just hasn't been important for you. That's a survival issue, we discard a lot of sensory information to make our daily lives simpler. When you open those floodgates and let it all pass, you let in a lot of stuff that's as real, and often more interesting than the stuff you usually let through. The patterns that you see when stoned, for instance, are an artifact of the way the nerves in your eyes are arranged and mapped into the brain. Beautiful noise!
...Psychedelics are a gift of nature that brings tribalism to people; they bring an understanding of the ecology of the planet and the interaction of all living things, because that's one of the first things you become aware of when you take psychedelics--how everything is alive and how everything depends on everything else. You go take a look at every indigenous culture that has a respect for its environment -- unlike the hierarchical approach of the feudalistic structures that the world is now run by -- and you will find that these people use psychedelics of some sort, usually in a regular, ritualized manner.
The music of the Grateful Dead is an important assistant to the revival of tribality. Because it has to do with the way things are. It's not somebody's idea about the way things might be, or the way things could be or should be. It's what it is. It's real music about real things. The whole thing is about a social movement. It's tribalism. Which is the only social structure that is truly human. The structure of the world today runs on feudalism--governments, companies; all those structures are feudalistic, arranged in a hierarchy which at the root of it follows Parkinson's law. That is, once you create a hierarchy or bureaucracy, it has only one purpose, and that is: To Continue. There's nothing else. But that has nothing to do with the tribal entity. The tribal entity exists so as to abide in harmony with its environment. It's something that benefits everyone, not just this one structure." -- Bear.
