    • Oliver Sacks said hallucinations are just part of the human experience. But it disturbs me when I think of a man like John Nash who was a genius completely halted in his tracks. Though, I can't imagine reading a Somerset Maugham book while listening to Leonard Cohen.  I talked on the phone for decent amount of time (a few years ago) with Dr. A.  He said people who suffer from HPPD are a sort of an odd group of people. I'm still not exactly sure what he meant.  Nevertheless, this world is changing at a rapid pace.  There is a great disparity between the rate of technological growth and the rate of human growth.  The very thing that is profound about the psychedelic experience is that time stands still for a moment.  You can sit on a bench and watch businessmen hurry off late for a meeting.  And you wonder what is so important? The world is not going to be solved; and taking a jackhammer to Lao Tzu's "What the caterpillar calls the end, the rest of the world calls a butterfly" is a giant waste of time.  People who are negatively affected neurologically  by a chemical not only reach an Ego-Death but often a Spiritual- or Sacred-Death.    Most people just think or scheme about things business related or moving up the ladder in socio-political manners.  But most people dont ponder or contemplate or reflect or dream, in what I find a normal way of being.  Sure, some of these yuppies or failed-idealism baby boomers might go to a yoga class or try meditation, etc.  But they dont get it.  You cant reach deep spiritual planes if you are slimy.  Slimy is not what youve done, but the "way" you think.  Here you can see a direct syllogistic correlating chronology between Carl Rogers, Abraham Maslow and James Fadiman, Slanislav Grof and Leary.  Socially you can see it from Socrates, Nietzsche, Bukowski to Robert Anton Wilson, George Carlin, and Eckhart Tolle.   There is a greater good but it is not for the group; it is only for you; it is only for you to be love; it is only for you to spread it.   Thank you
    • The problem is, I don't think I'd know "normal" if I experienced it.  
    • Found something weird : When I focus on something really hard with my eyes, everything starts to move. Now that's not the weird part. What I noticed is that I would get "exposure" shifts, like the brightness changing randomly. So I filmed my eyes while focusing on something, and weirdly enough, my pupils dilate and constrict randomly for no apparent reason. What the hell.
