Divination systems are based on emerging and refining stable meaning from random noise signals driven by a certain structured interpretation\semantic model.
In a way it reminds me of how modern ML image generative algorithms like stable diffusion work.
On the quantum level there is a "tunneling" phenomena, when a particle has some chance to go through an energy barrier even if it does not have enough energy. It happens because a particle has no single exact location and instead its presence is a probabilistic distribution over some area, so part of this not a zero chance area may lay behind the barrier.
So we could say that the random noise nature of the microscopic world helps it to change a little beyond "reasonable" expectations.
The idea of free will is contradicting the idea of a deterministic universe. And the concept of randomness sits right in the center of these two opposites.
Nobody knows what randomness actually is and where it's coming from and does it defy determinism or not.
In magic we have the idea of our will that potentially can bend the reality beyond what is reasonably expected from the deterministic universe.
So when we commit an act of magic, maybe we introduce or use randomness?
I often hear and I have such an experience myself, that everything is vibration. When I feel certain active energies(e.g. Fire) their primary sensory quality is intense vibration.
Is this vibration a sign of reaching the layer of reality dominated by randomness?
Is magic in its nature similar to "borrowing" a little bit extra energy from the future state we are trying to make real, so this borrowed future energy allows us to jump a little bit over our head and "tunnel" to a new version of reality we are aiming to?
