Three teachers stand before you. You choose the teacher that offers the lessons that are most intriguing to you at this moment in time. Each teacher has lessons to offer that can enhance, synergize or reinforce the teachings of each other. Right now DMT calls to you. Nothing wrong with that.
DMT is not always the most useful in my mind, if we are assigning values. Sometimes I don't have a clue what to do with the experience, at times either not remembering the totality of it all or it just being so absurd and chaotic that there is no way to make heads or tails of anything. I find DMT to act as more of a reset button in my mind. Takes me out of the ego sometimes entirely and that in and of itself is calming, liberating and profound in many ways. This kind of experience is so strong that it can feel like mushrooms or LSD could never hold a candle to it.
However this is not the case at all. I have had very strong experiences with other psychedelics that DMT could never provide. For one a certain level of coherency and the "I" is largely still involved, sometimes taking a backseat but nonetheless much more present than in the DMT realms. Mushrooms feels like the most like a teacher to me, I have specifically felt like a lesson was being conveyed. Higher doses of mushrooms can feel and present very similarly to DMT as well. LSD allowed me for a child like wonderment. A certain level of completely letting go of reality can be achieved with higher doses of LSD, the mind becomes entranced, massaged with light and reality bends. MDMA melted me into a pool of love.(Best way I can put it.) I became love itself and my ego was hardly there at all. Aya broke me down and built me up from the foundations up, showing me that I was the architect all along.
I have had breakthrough experiences with all of these psychedelics and would never say that one is better than the other, more useful than the other, better or lesser teacher than the other. They each hold their weight in gold.
You may have rephrased your question, but the answer remains the same. A question I pose would be 'why you feel DMT is the most useful or relevant to you at this moment?' I think if we talk about that we could get to the nitty gritty of what you are ultimately getting at. I totality get where you are coming from though. I do. Just work with it until another teacher calls to you or the classroom bell rings to change classes.
