" has to do with shamanism that is based on the use of DMT in plants. DMT is a neurotransmitter that, when ingested and allowed to come to rest in unusually large amounts in the synapses of the brain, allows one to see sound, so that one can use the voice to produce not musical compositions, but pictorial and visual compositions. This, to my mind, indicates that we're on the cusp of some kind of evolutionary transition in the language-forming area, so that we are going to go from a language that is heard to a language that is seen, through a shift in interior processing. The language will still be made of sound, but it will be processed as the carrier of the visual impression. This is actually being done by shamans in the Amazon. The songs they sing sound as they do in order to look a certain way. They are not musical compositions as we're used to thinking of them. They are pictorial art that is caused by audio signals."
