The inner hearing is sealed under flesh, so the word that would loosen the lower nature lands instead as an insult. The ear is uncircumcised, its opening covered by the excess of the animal self, and truth cannot enter where the crude growth has not been cut away.
Circumcision is the trimming of that excess, the removal of the surplus lower nature so the passage lies open. Because the flesh takes no pleasure in what would weaken its grip, the very sound that offers release feels like reproach, and a person so covered cannot hear.
Ear: the inner organ of hearing, sealed shut when the excess of the lower nature covers its opening.
