I have never experienced the effects of Salvia but am moderately familiar with the indescribable.
I really liked how you tied in the reference to Wittgenstein bringing it back to the interplay between language and metaphysics, between our use of meaning and, for want of another way of saying, the presented World.
In regards to psychedelics, the question remains, what is it exactly that is shown?
To me it seems that there is a certain immediacy, and an awareness of presence, that is hard to deny and yet perhaps it falls outside our usual questions of what is true or false, real or an illusion?
What seems undeniable is that the World is in a sense undeniably inexplicable, and perhaps we need to accept that while our words and theories may give us sign posts the possible ways of seeing what is shown are inexhaustible?
Its a humbling lesson to be reminded that what exists is, in a sense, beyond us, and our understanding, even while we interact with what is shown everyday.
And perhaps it is good to be humble about what we think is true or false and to have our foundations shaken sometimes to remind us that there is more mystery to the World then we can ever describe.
Cheers.
(I ramble, but hey, i like to do so). lol
p.s. thanks for the heads up about your new experiment on steemit.
