My best, most educational, most deeply therapeutic and life-changing acid trip was also my worst, most traumatic, most frightening, and potentially most life-destructive trip.
LSD is not brain-candy; it’s not a “recreational drug” in the sense of being a good thing to use for “fun”. It can be thrilling, and deeply moving, but it is first and foremost powerful and that power can destroy as well as create.
The second thing to understand is that when people drop acid, they often feel while they are tripping as if life in general their life in particular, all the big question stuff, suddenly makes sense, which is (as you can imagine) very exciting. And then as they come down, less and less of that seems to be something you can hold onto, it ceases to make sense or loses a dimension or something, you cease to see your new “insights” as important or special.
Some people deal with that by shrugging and dismissing the entire “important insights” stuff as dismissable. (IMHO, they are the ones most likely to get in trouble with acid if they continue to play with it).
At the opposite extreme, others get serious about it the way some folks get serious about religion or focused meditation – they try to replay the things they experienced when tripping and extract more permanent insights from them.
I would explain it like this: your mind always tends to use shorthand to represent concepts on one level when thinking about how one concept affects or interacts with another. For instance, if I ask you to think about the relationship of marxism and trendy Italian cooking, and how they each interact with Islam and western medicine, you aren’t going to be simultaneously holding in your head the full philosophical thought-system of marxism and the entirety of the other theories and disciplines – you’re going to conjure up a sort of shorthand token that sort of encapsulates what marxism means to you, in order to visualize it in relationship to the other tokens that represent the other mind-sets you’re thinking about. We do that all the time. When I tossed out those four incongruous examples, some of the things you know about each of them probably came to the fore of your mind (working-class Italian cooks or marxists eating chicken parmesan while discussing politics? dietary restrictions in Islam? relationship between cuisines, dietary restrictions, and what’s healthy for you to eat?) because they were interesting in relationship to the other three. With me so far?
Well, LSD is the mental connection-maker, and in very short order you can conceptualize stuff for the first time, then “tokenize” that new understanding in order to consider how it fits into other patterns, then “tokenize” that as well. The understandings are (usually) real and (usually) valid, but often that which the tripper understands and is so excited about is understood only in a very compressed shorthand form, a form that takes a lot of unpacking before it could be put into words and explained to someone who hadn’t thought of things in those terms before.
And as you come down, it is very very easy to lose track of what vast strings of those tokenized shorthand things represent.
Finally: the creation of those “tokens”, by necessity, usually involves seizing upon or creating an oversimplified symbolic thingie that represents a more complicated concept, but the combination of the great excitement of insight & understanding plus the sad fact of losing track of what it was they stood for can cause lots of trippers to attribute the entire importance to the oversimplified symbol.
