1.18

Ascending the hall on the winter solstice, he said: "Yin reaches its extreme and yang lies submerged, spreading the way of generation and growth. Empty and congealed, it shines, dividing aside the conditions of establishing transformation. One directly reaches the point where looking down and looking up accords with transformation, and responding and meeting are without lack. Do you all understand? When the mirror is clean, who dislikes different images? When the valley is empty, it naturally responds with the same sound."
