IME set & setting are everything when it comes to an awesome LSD trip.
I have had the privilege to experience thousands of these trips in the last 35 years.
Probably the biggest & most life-changing event for me took place high in the jungle mountains of Sri Lanka with a small cluster of very secretive, very elite & very
different Buddhist monks who, for whatever their reasons, used LSD & Cannabis as meditation tools.
At one point, after having lived, studied & meditated with these monks for a couple weeks, the head monk had me sitting in an isolated shed (for the lack of a better term; it was an adobe-like shed, approx. 10'x10', with a thatch roof that appeared to be where they stored their firewood). He had placed a pile of human bones in one corner & had instructed me to meditate on the bones & my impermanence.
Approximately 24 hours into this "exercise" (I had completely lost track of time at that point), the head monk came in & offered me what he called a "4-way Gooney Bird" that he had stashed from the 60's (this was in '83/'84) that was purportedly made by none other than Owsley "Bear" Stanley himself. He asked me if I was familiar with Owsley's acid & I implied that I was, on a theoretical level, but of course had never dreamed that I would ever have the chance to ingest any of it.
The head monk then asked if I wanted to imbibe in a "whole hit" or a "half hit" & also implied that each quarter hit was 250 mcg (thus making this tab of blotter, which was the size of 4 normal-size blotter tabs "4-way" I suppose). Needless to say, I went for the whole hit.
It hit me rather quickly...The head monk had taken one along with me...During the come up, my body grew increasingly hot; I began to feel woozy & slightly nauseated (not a "purge type" of nausea; more like a nausea caused by feeling so hot, faint & woozy). He sensed this...asked me if I was feeling that way & I confirmed I was with a nod...He instructed me to scoot my seated body (I had been in full lotus position for a good 24+ hours at that point) over to his chair that he had had helpers place in the shed (his body was wracked by ankylosing spondolitis, a severe spine deformity; he walked like a spider with two canes) & situated my spine up against his shins. As soon as I did this I immediately felt better, lighter & full of transformative energy as never before.
Feeling somewhat "solid" again (as solid as I could considering the LSD was strong, potent & coming on very quickly), the head monk suggested that I do some yoga to stretch out my aching, stiff muscles after such a long sit...I obliged & it felt amazing to do so.
After a short while of yoga asanas, the head monk waved his hand in a showing, sharing gesture & said, "you should go walk around the gardens; it'll do you good". These gardens he was speaking of were some of the most beautiful I had ever been in & due to the overwhelming strength of the LSD I had consumed about an hour & 1/2(?) earlier, the bougainvillea & the roses were reaching out to me in a most pleasurable, intense way; talking to me, as it were, without words. I cannot recall the exact conversation, but suffice to say that it was the first time, in this lifetime anyway, that I felt as though I was having a serious telepathic conversation with a non-human entity.
I wandered throughout the gardens for what seemed like eternity but was probably a couple hours; meditating on every step; meditating on the flowers & trees & grass & sky & water in the various little ponds & streams. To me, at that point, I was in heaven & felt very, very powerful mentally, spiritually & emotionally (I know that's a very vaugue way to put it, but words fail me at this point).
At some point I made my way back to the head monk's little cabin where he slept & meditated. He asked how I was dong & I replied that I was doing better than I ever had been heretofore. He then suggested that I go back to the shed with the firewood & the bones & meditate some more. I took his suggestion to heart & made the short walk back to the shed through the gardens once more.
I seated myself back down in full lotus once again & proceeded to focus...I don't know how much time had elapsed before I lost all "I" & for the first time, in this lifetime, melted into the Void.
Nothing & everthing at the same, instantaneous moment; forever; eternity; no-time...
How long I stayed in that state, I do not honestly know, but when I came to & opened my eyes, the head monk, along with two of the other monks were standing over me with big grins on their faces...They said, very happily I might add, that I had died & had attained Samadhi...I fully understood what they meant. It was an incredibly life-altering time there in those jungle mountains.
They helped me to my feet & the head monk instructed me to gather some firewood from the shed we were still in & to go build a fire in the fire pit at the center of the gardens. The moon was full & the flowers & trees were still overwhelmingly, beautifully communicating with me.
I got the fire built & going & we sat around it for the remainder of the night...As the first light of dawn filtered into the sky above us, we had a wonderful conversation about how many colors one could see in just a short period of time. Some helpers brought in miso soup & fruit for breakfast. It was divine... I hadn't eaten in roughly 48 hours...After breakfast, the head monk lit up a joint & we passed it around. Daylight in the gardens was breathtaking at this point & the acid still gave no signs of letting up nearly 14, 15, 16 (?) hours after ingestion...
I didn't fully come down from that dose until a good 72 hours after ingestion.
Freedom's so hard
When we are all bound by laws
Etched in the scheme of nature's own hand
Unseen by all those who fail
In their pursuit of fate
