Culture is a perversion. It fetishizes objects, creates consumer mania, it preaches endless forms of false happiness, endless forms of false understanding in the form of squirrelly religions and silly cults. It invites people to diminish themselves and dehumanize themselves by behaving like machines.
It puts people who are into this psychedelic thing in an entirely different stance from all other spiritual seekers, because all other spiritual seekers are furiously seeking. Psychedelic people are holding it back with all their power, because they are in the presence of the mystery. And then the trick is to get a spigot on it so that it can be turned on and off rather than coming at you like a tidal wave a mile high and twenty miles wide.
In other words, all these things you might cling to, Catholicism, democratic ideals, Hasidism, Marxism, Freudianism, all of these things are exposed [through use of psychedelics] as simply quaint cultural artifacts, painted masks and rattles assembled by people of good intent but clearly not great grasp of the situation.
