When the shoe fits, the foot is forgotten; when the belt fits, the belly is forgotten; when the heart is right, "for" and "against" are forgotten. There is no change in what is inside, no following what is outside, when the adjustment to events is comfortable. One begins with what is comfortable and never experiences what is uncomfortable, when one knows the comfort of forgetting what is comfortable.
ZhuangziHence it demands the emptiness of all the faculties. And when the faculties are empty, then the whole being listens. There is then a direct grasp of what is right there before you that can never be heard with the ear or understood with the mind.
