It's interesting how perception is something that is a recurring theme with you. Your own perception of the world is something you have thought deeply about.
How many senses do you think the average human has? Can you generate enough mental energy to use the mind to feel? Can you condition yourself with your thinking to feel with your brain? Or does that only happen when high?
I think our senses inform our consciousness, which has evolved to interface with the world in this way. "This way" is an organization of flows. A flip in the sign of the flow is what I consider alpha energy (an edge) and the changes in intensity i consider omega energy. A flame (where the edges are the alpha analog) is a good metaphor for how i think about it.
I believe a person can calm their minds enough to feel energy in their body. I think of this as nervous energy, but i do find that they move up and down the center of my body and gathers at the chakras like the people who also tried just sitting like four thousand years ago thought.... No i do not need to be high to feel this. I find i shiver and yawn as the tension dissipates high and low as appropriate.
As regards senses....idk, we put edges on things but I'm yet to find a real one beyond the flip of the derivative's sign....the rest just kind of float away up close......
I think that for a long time we have been in a period where the alpha energy (edge definition) has dominated human progress. And i think we are on the way to the emergence of densities overtaking edges as the primary way forward. Think wifi and machine learning over wires and swiss clocks.
So, for a clever answer, people have one sense, and that is the sensing of densities (since flows are what they become at the neuronal level right....) But our embodied experience? Five we can communicate about evenly with linguistic references to shared spatial experiences....but man idk about the non-shared-spatial-experience....that's where art/spirituality (at the density of spirit i.e. liquid i.e. the edgeless.....) comes in.
Btw: can you feel with your mind? Idk, but i think you can feel your mind. Put your hand on your desk and stare and the nail on your pointer finger as steadily as possible. Feel that buzz of your attention?
The word attend as in "attention" comes from "a+tendere" in latin (in spanish that would be related to tener, yes) and it essentially means to reach out and grasp.
Sooooo idk what to call that (a sense?), but everyone feels it like a static hum in the background of their every instant imo.
(Yeah this is monkey mind etc...i find the mind waves described by shunryu suzuki in zen mind, beginner's mind to be more resonant).
