One way to think about what psychedelics are is as catalysts for language development. They literally force the evolution of language. You cannot evolve faster than your language because the language defines the culture of meaning. So if there's a way to accelerate the evolution of language then this is real consciousness expansion and it's a permanent thing. The great legacies of the 60's are in attitudes and language. It boils down to doing your own thing, feeling the vibe, ego-trip, blowing your mind.
