Hello.
First let me say that everything written here is just my "view" based on my own personal experiences with dealing with the spirit realm so I'm not trying to portray anything here as an absolute fact..just my opinion.
OK...
I have been taking psychedelics for almost 20 years and I have been having "God" type experiences ever since I began. Instead of "God" I prefer to call it "The Creator" but that is just because I feel it to be a more accurate title.
These types of experiences do happen but not all that frequently, in fact I would venture to say most psychedelic users don't have them...If you are someone that has this type of experience then you are probably one of the "chosen". By "chosen" I mean The Creator has a special job for you of some type and is trying to get you to "wake up" to your life's purpose.
The first time I had such an experience was with LSD. I thought I saw God Himself, face to face..(I took LSD for 11 years before I discovered DMT)
I eventually came to understand that it was not the ultimate divine father that was visiting with me while I was on LSD but actually what I was seeing was an Angel, a fragment of the divinity.
I have been taught that although there have been exceptions, no living man is generlly allowed to look up on the face of The Creator except for while in dreaming. This is because we as humans are too impure to be in the company of the Holy King...it would be something like a moth flying into the Sun's Corona.
On DMT however it is possible to hold an audience with the creator because dreaming and DMT tripping are similar functions of the brain/soul. While, I myself have never been allowed to behold the actual "Creator" as of yet..I am still quite satisfied with what I have witnessed thus far.
So to conclude my long winded answer I will say that yes, I have seen "Godly" things on LSD, DMT,Mushrooms, Mescaline and 2c's but the most sacred experiences I have had have been on Ayahuacsa... I happen to believe that Moses used an Acacia version of Aya to assist in inducing visions. (I'd say Salvia is a little trickier to work with)
