Deep within Shinto temples in Japan you find only a mirror. It is a symbol and a riddle. The risk there is of turning in upon the Self. But the Christian knows that the Self is the image of Christ. And Christ is the faithful mirror who reflects the truth not only of creatures and objects, but also of the Self that is no longer an undifferentiated abyss but the interior expression of a face.

See the Lord is our mirror:
Open your eyes,
Look into it,
Learn what your faces are like!
Odes of Solomon, 13
