I note that "It's like tripping your balls off on LSD" is missing from the list. But, funny thing: It's the most accurate. Instead you get a bunch of gobbledygook about death, eternity, and direct messages from god. The fact that you might just be having an episode of impaired cognition does not actually enter your brain. Let's not make this more complicated than it is.
Anything with the phrase (paraphrasing) "but I must warn you, you must be surrounded by evolved people" sounds so incredibly condescending and pretentious it really shows how these people see themselves as superior to others, like your friend who travels a lot and brings it up all the time. Except his stories are rational and meaningful, while stories about tripping balls are so subjective, they're meaningless. Yes,…
That's all it really means... not that people who take acid or drugs or any better than anyone else. It's just an openness of mind that doesn't really put labels on things and can just go with whats said. It's a state of mind that doesnt automatically as a knee jerk reaction shut someone elses (subjective) opinion down as to what wisdom they can learn in a state of ego-less-ness.
After all, you may think the article sounds pretentious or condescending, but to me I see just what it's saying in such a wonderful non-judgmental way. I think the fact that point might not occur to some is, in essence, exactly what its referring to. Kind of self reflexive :)
