47. The darkness in the sun is the vitality of the true moon; the "moon
cavern" is not on the moon but on the sun. That is why it is called the
"moon cavern," for otherwise it would be enough just to say the "moon."
48. The white of the moon is the light of the true sun. The sunlight being on
the moon is what is called the "root of heaven" Otherwise it would be
enough just to say "heaven."
49. When the sun and moon are separated, they are but half; only when they
come together do they form a whole. This is like the case of a single man or
a single woman, who cannot form a family living alone; only when there
are husband and wife do they amount to a family.
50. But it is hard to represent the Way concretely. If a man and a woman are
separated they are still individuals, but if the sun and moon are separated
they do not form a complete whole. What I am saying just brings out the
point of communion, so I do not see duality; you just cling to the
separation, so the separation has taken over your eyes.
