I'm just another student that is a part of the whole. with that been said, i have some philosophical point:
old languages were engraved on stone tablets, music was engraved on plastic phonograph discs, data in engraved on memory discs, and I can conclude that our thoughts and memory are engraved on our nerves system.
On DMT and other psychedelics, we all talk about the geometrical shapes that shows while dosing, in my humble opinion i guess that these geometric shapes could be another interpretation of our thoughts and memory, a code that is universal, a cosmic language if you wish! Maybe If we can put up it's rules together, then we can communicate with all forms of life and with the creator himself! Just a crazy wild thought!!

That's a great way of looking at it. My personal interactions with the shapes is that I've seen them becomes things, architectural things! Maybe my mind bends them without me realizing it. I haven't given much thought into actually controlling them rather than just seeing them.
