Don't downplay that epiphany, I think it's a very fundamental realization, and one that not everybody gets.

I've done the MDMA/DMT combination before, with similar logic.  I have a theory that we drive ourselves to do that as a form of ego self-preservation. Total self-preservation of the ego would demand that you throw your spice away and never speak of it again! Since we're apparently bent on humbling ourselves like this, taking some other drug alongside DMT is a compromise.

It's as if the ego is saying to you: "OK, go ahead and reveal the illusory nature of the ego, but be really high on substance X at the same time so that you gratify the ego."  Yes, it's contradictory. The ego often is. 

So perhaps it's best to ignore our ever-babbling egos, and ride this horse bareback.
