Well i think you answered your own question. Of course question it, if I have learned anything at all it is that all of my understandings and conceptions are null in the face of it. Everything I think I know is wrong. But, at least try, why not.
Maybe it is best to then approach it with a simple word like 'deep' which doesn't mean much without context, akin to 'it'.
I am using it in the context of my own experiences that I would describe as mystical. Faced with the infinite, the only action left is surrender.
Mescaline and psilocybin have both brought about these experiences, but so has stone cold sobriety, and a bit of desperation. Reaching that point of surrender is rarely fun.
in my experience, psilocybin was everything DMT but a step further, DMT gave fantastical experiences, visually unparalleled, completely different dimension, and demonstrated the same principles. But psilocybin was personalized, it allowed me to surrender in a way I never thought possible.
It could be more due to my relationship with psilocybin vs my relationship with DMT
mescaline went even deeper, to a place in my heart i never knew existed.
you don't need to take drugs to surrender, to bring about such experiences. So there is no reason why they could not happen on 2c-b or DET. It depends entirely on you, not the substance. However if you chase the euphorias of 2c-b or DET you just resign yourself to suffering the egoic game of highs and lows. But there seems to be an inherent quality of some of these compounds which are more capable of bringing about mystical experiences, 'deep'.

regarding another n-alkyl tryptamine, MPT, i had a breakthrough experience that was indistinguishable from DMT, except for maybe it had a longer duration and some characteristic strange sensations that are common with the propyl subs. But the core message of the experience was undifferentiated. It was DMT. So I am sure this compound goes deep. But i also felt no reason to take it again because it could not bring about any new dimension of the experience that DMT could not. Infinite REALLY means infinite... I think the methyl group is necessary for the breakthrough experience, relative to DMT.
