I want to pick up some thoughts of my own to this question of the drug-assisted mystical experience and your thoughts surrounding that. My own experiences have been unaided that way and were spontaneous openings, that peak experience I mentioned in the other post. From my understanding a drug-assisted experience can be profoundly awakening and life-changing as well, but I think it would have to have some similar underlying condition as the spontaneous peak experience. In other words the 'readiness' of the experiencer.
To just simply take some drug recreationally at a party and have a profound experience, like a DMT experience, might not have the same degree of impact on someone's life as someone who was needing some sort of breakthrough psychologically and spiritually. If someone taking DMT were to do so through some ritual form as part of some spiritual seeking, it could have much more meaningful impact than someone just getting high as part of some thrill-seeking experience.
But then again, even the "seeker" might in fact not actually be ready psychologically, emotionally, and spiritually, for their experience despite believing they are. Therefore the experience gets "dropped" because like the proverbial tea cup story, there was nowhere for the master to pour tea into the student's cup because it was already full and so it spilled all over the table, as opposed to being empty and ready to receive the tea being offered. By the same token then, even the "thrill-seeking" kid at the party, may unbeknownst to himself on a conscious level actually be ready to receive, and 'inadvertently' taking the drug opened himself to what he deep down inside was unconsciously seeking. In that case, it would have a lasting effect.
Why it seems that the spontaneous 'natural' peak experience is more lasting and life-changing would probably have more to do with the conditions for it in the first place. It occurs, I believe as a sort of transcendental 'breakthrough' of the subconscious mind to the conscious mind. The conscious mind was in 'tension', on a deep level, just below the surface. The tension was there, but not ready for the fully conscious mind to be able to look consciously at that material down there. Then, something happens where the conscious and subconscious mind knows you are ready to 'hear' that message, and "pow!", a crack forms in the floor and the subconscious mind comes blasting through and presents to the conscious mind that material from the Depths.
How that manifests to the conscious mind can take many forms, from a profound connection to all of life, to visible visions, such as deity forms, to light radiating in everything, and so forth. These forms, especially deity forms are symbolic manifestations of the deepest levels of our consciousness. The forms they take are what the conscious mind supplies from it's symbolic reserves offered to it through their culture's pools and languages. They are not the "actual" Jesus for instance, or the actual Avalokiteshvara with an actual 1000 arms, so there is no way "scientifically" to say those are "real" in the way they are experienced. However, they are real in that they are the same type of experience, manifesting the same sorts of archetypal forms from the person's culture.
What has happened psychologically and spiritually is the person was ready for this breakthrough and they allowed themselves to expose this stuff from down deep in our
preverbal subconscious mind (as well as our emergent unconscious- another thing, transcendent potential) which is constantly aware of stuff for us that we in our conscious mind can only take in trickles, or odd impulses as it puts pressures upon us.It's all about bringing those awarenesses at those levels, to the awareness of the conscious thinking mind which is normally just processing the daily crap of life it its symbolic systems of mental objects. Now we are actively, consciously including all this material from the subtle and causal realities of our being into the actively conscious mind. The forms of languages these take for the conscious mind become mandalic, or salvific, highly symbolic forms, etc.
In reality, all of this is what a good meditation practice does for a person, but where it is regulated and taken as what I like to call, 'lessons in the Light', rather than some abrupt eruption where you are shot up out of the volcano's mouth in a blaze of glory! I take some qualified exception with the Zen approach to simply
ignore this material, but I'll save my comments to that for another post.
So to the drug-question, again I think it all has to do with the 'readiness' of the conscious mind to bring up what the subconscious mind has for it and be able to actively begin to process it, even if it interprets these things as actual manifestations of actual deities. Even at that 'literal' level, it is still acting symbolically on the person. And so to now believe that "Jesus" is there for me, does have the effect of letting the person reach beyond their mundane 'normal' ideas of reality to the higher Self, through the agency of archetypes. As Jung call these, "symbols of our transformation".
There's other things I'd like to touch on with this, such as how peak experiences are fairly common, but a lot of people are not ready to pay the price to talk about them with others for fear of being judged too outside the culture or group, of fear of being call crazy, etc. There is also the heavy price to be paid that you end up without a lot of support as few have trod the path of the mystic, and so it's easier to just 'forget about it' or tuck it away somewhere and do nothing with it and just go on with being 'normal'.
So again, I think this all really has much more to do with that tension between being and becoming, that is the necessary condition where the peak experience takes root and grows, or is simply set aside as the mind is not ready to do the work in the hope of someone integrating what was exposed to it. It's really the "soil" the seed is sown into, to borrow from that parable of Jesus. The ground has to be prepared, it has to be able to receive, and to me that is a far deeper question than the mystical experience itself.
I could write a whole book on this stuff... oh hey, I am.
