Rumpelstiltskin, the Matter 2 example. (In-character, brackets are OOC)
Straw exists, and that is all it is... as far as the Dweller in the Cave know.
1) As I focus, I position my focus's slider at the opposite end, segment AB (eikasia). The straw is false, just an illusion, a shadow of its truth. While there is substance there, it is not being seen for what it is... how nostalgic, that this reminds me of when I was just looking at shadows dancing on the cave's walls myself, before I was brought above {Awakened}. I mentally being to grasp at its reality, that it is gold, fortifying my will, I begin the chant {translated from Attic} "
function begs thought, thought grants form, for we think and thus things are".
2) I slowly move the Slider of my focus into the phase of the objects true self, pistis, focusing on the motion of the slider being the same as the straws motion through The Line, from the illusion that it is to the reality that it can be. I force it to be what it is with the mere alteration of my thought. I think, therefor it is, and it is to lose its false form, its illusion fades away, for all to see now the true form of this gold.
