I've been eating acid since I was 16, that's literally half my life. To me, it is a TOOL, no more. It allows different perception yes sure but you have to know how to use it or you'll just fry yourself. It's not a recreational substance in my opinion at all, and going at it for shits and giggles is stupid.
Look, I am sure it is a 'portal' to many things also. But in a sense that the only reality there is is that made by your own brain, EVER. There is NO mutual reality. There is NO assurance that green looks the same to me as to you. So if you want to percieve a connection to other dimensions or whatever you will. Who am I to argue whether this is real or not?
A question: Does it MATTER what others think?... It does only if you want to fit with a certain paradigm. Acid doesn't drive you crazy, it does however isolate you if you're not fucking careful. Realize that your new-found realities will sometimes exist in severe dissonance with that of your brother.
And I stress that it is about perception only. As God Here said, there is no infinite wisdom to be gained, in short, there is no shortcut around the human condition.
Make of it what you wish, but in the words of Aldous Huxley, be vigilant with your mind. Watch your step, cuz.
Acid however doesn't lie man... It might not give you wisdom as such, but if your life's a mess and you're constantly cocking up, it'll let you know, you won't be able to hide behind any excuse or reason for shitty actions. It'll kick you in the balls HARD.
ALWAYS seek the benefits. I repeat, acid is not recreational, and used as such is a reckless companion...
