Mirrors Reflect the True Self

Mirrors reflect light in the same way that you would see it with your eyes when looking at something, except if they are convex or concave. A to qang chin was said to cast a reflection that showed the image the back, as in the back of the mirror, as if the light had penetrated the metal. And he writes that this might have been due to a polishing technique that caused imperceptible irregularities on the mirrors surface that corresponded to the raised pictures on the back.
