Pathos/Heart is the Emotional-Neurochemical Circuit — feeling and meaning. The wetware between the software of Mind and the hardware of Body. This is where concepts become real: the idea that has acquired its emotional charge, the understanding that is felt rather than merely known. Aristotle's Pathos — what an audience feels, what a being undergoes. The neurochemical transmission layer named as the seat of lived emotional experience. The Egoform's primary operational blockage is at the Rationalization shear zone just above — where conceptual energy should acquire emotional charge and become felt meaning. When that shear zone is blocked, Heart is starved of incoming signal and begins generating its own — typically through negative neurochemical feedback loops. The alchemical fire at this level is what burns through the Ego-Mass.
Heart entering Body — felt meaning becoming physical action, somatic response, making. The emotion becoming gesture, art, movement, sound. Physical vitality and genuine expressiveness in flow when this transition is unblocked.
