On ayahuasca, i've felt i had reached the state of utter bliss. On 5-MeO-DMT, i become it. I am not "in a state", i am this state.
The sensation is not physical, it's emotional.
The only thing that hints at a physical sensation is a feeling of unbelievable freshness; as if a wind was blowing through every atom of my body, and between every particle of those atoms. So actually, it doesn't feel as if my physical body was feeling this freshness, but as if i was feeling with my soul instead of my body.
And my soul is in a state of ecstasy that no one can imagine without living it.
The experience is simply impossible to describe because it doesn't compare to anything in our world. I'd like to say that it's the most overwhelming experience imaginable, but the word overwhelming pales pathetically compared to the reality of the experience... which is not imaginable anyway. This sensation doesn't exist in our world or in our wildest dreams and there are no words to start describing it. It's not any more possible to imagine it than it is possible for a blind person to imagine what sight is like. We could call it bliss, but we would then be mistakenly tempted to compare it what we call bliss in this world. And it just doesn't belong to the same scale. If the scale of sensations in this world goes from –10 (absolute pain) to +10 (bliss as we can experience it), then 5-MeO-DMT brings you to +100.
