Rushing with my words, but if you know how to work with the chemical...in my opinion it's not matched. I think my wording ended up like that, in terms of its spiritual value, from comparison of other things available that aren't drugs. Regardless that it's my opinion that I feel LSD is the best psychedelic, obviously I'm working with it differently than others that gain higher appreciation for other things.
That's cool, I don't think there's anything people can take issue with in personal opinions like this. What may or may not be the case for you as far as derived value from one psychedelic or another is not anything that other people can dispute, since there's no way to objectively experience another person's experiences. It would be totally awesome if there was indeed a way to transfer the data streams from all five of one person's sense to a different person entirely (I'm so down to experience lesbian sex, would be great), but there's not, so value judgements made on the basis of ones experiences are pretty much unassailable and off limits as far as debate, provided that those value judgements aren't extended to other people or presented as objective fact (like 'I find acid to be the most spiritually useful psychedelic, therefor it is the most spiritually useful psychedelic for you too, or for everyone, cause I say so', etc).
As for 'knowing how to work with it', I definitely buy the idea that there are ways to engender spiritual feelings to either a more frequent or greater/deeper extent than might otherwise occur by developing some sort of set of techniques and practicing them in such a way as to hone those techniques into the most effective tools as is possible. Would you perhaps care to elaborate on 'how you work' with acid? I'd be very interested in hearing about those techniques and perhaps attempting to utilize them during my next acid trip.
I don't however think that the reasons that you find acid to be the most spiritually useful psychedelic while others may disagree and have alternate choices for 'most spiritually useful' psychedelics can be ascribed solely to your 'working with it differently'. Instead I would focus on the different forms of subjective value that can be derived from psychedelic experiences. For example, one of the most powerful spiritual experiences I have had was on 2C-B
I'm a habitual daily-using heroin junkie, as you may well know, and during that trip I took a shower that cleansed by soul and mind, not just my body. Upon getting dried off and dressed I had the realization that everything that can be broken can be repaired. The caveat, which is not a negative thing, is that the repaired object will not be exactly the same as it was before being broken, cracks will still show perhaps, though those fractures may be fully repaired in structural terms. So applying this to my life, I can, when the time comes that I am fully motivated and dedicated to getting clean, repair all the psychological and spiritual damage that has resulted from my addiction. And in accordence with that caveat, I will not be the same person as I was before I got hooked, or the person I would be had I never been hooked at all. So though I can heal the wounds, scars may remain, but those scars aren't a bad thing because they'll remind me not to harm myself in that way again.
So this was a very spiritually powerful realization. However, it isn't spiritual in the same sense as the cosmic spirituality derived from an acid trip. And my first experience of ego loss, on a half ounce of mushrooms in a forest, was the experience of the universe dying and being reborn or better said reincarnated, hundreds millions of times per second. That was itself immensely spiritually powerful, but again in a different way from acid. And then I have also had incredibly powerful spiritual experiences on acid in the traditional sense, which you allude to.
So I personally don't think I could pick one psychedelic and tout it as the most powerful. That's not to say that it's wrong to do so if you can indeed examine your experiences and conclude that one psychedelic trumps all others for you in a spiritual sense. I just personally can't do that myself. For me, I find that there are uses and aspects of many psychedelics – but not all, 2C-I being an instance of a chemical that I find just utterly worthless and incapable of generating any meaning whatsoever – that are all equally valuable, but understanding that they hear their value in different ways. Still, I'm sure there are many, many people besides yourself who would indeed be able to pick a single psychedelic as being the most powerful for them, and doubtless many would also choose LSD.
Anyway I'm definitely interested in hearing about your metaphorical toolkit as far as 'knowing how to work with acid', should you be interested in talking on the subject!
EDIT: I guess the argument could be made that the experiences I described are not 'spiritual' in the manner of acid. That they may be powerful, and have real psychological implications, even that they could indeed have an effect on what I would describe ask my 'soul', though I don't believe in souls as separate things from my physical body, in the religious sense, preferring instead to think of it as being the parts of my conscious and unconscious mind that could be described no other way with any accuracy than to bundle them together as 'my soul' or 'my spirit', but with an understanding that this aspect of myself is still generated solely by my brain, is an integral part of my being, but possesses no supernatural aspects and will crease to exist when I die.
But anyway, leaving aside that digression about what 'my soul' is, I think trying to argue that those experiences I had that I feel we're spiritual but not in the exact manner of acid are instead not spiritual experiences but instead simply powerful psychological experiences that may have impact on my psyche or my soul is a restrictive use, and an arbitrarily picky use, of the word 'spiritual'. Those experiences sure felt spiritually powerful to me, in the sense that they touched a part of my being that is not associated with the rational or irrational reasoning performed by my mind. They touched a part of my being that is in some senses an antithesis to my conscious mind, a deep portion of my being that is generally off-limits to my conscious control, that is also the part of myself that would be touched by religion, were I religious. That sounds like a spiritual part of myself to me ears, and so I label those experiences as spiritual, while ackgnowledging that this part of myself that was touched by these experiences can – just like my conscious mind – be stimulated in a variety of ways. One of those ways is the 'cosmic and spiritually inclusive experience' that acid produces, while the ego death universe creation/destruction cycle mushroom trip and the realizations that day on 2C-B each touch that spiritual part of myself as well, in unique ways relative to eachother or to the traditionally spiritual acid experience.
