...That's why Bodhidharma says, "Devise no word." And if you
have already devised, undevise them, drop them. This is one of

mo chao – when you are not devising any word. Mo means
serene or silent and
chao means reflection or
awareness. Reflection does not mean what it
usually means in English, it does not mean
contemplation. It means a mirror-like quality. It
exactly, literally, means reflection.
Mo chao
means serene reflection. The lake is silent – no
ripples. It reflects perfectly. It is a full moon night
and the full moon is reflected in the lake.

is far more beautiful than the moon in the sky.
Something is added unto it – the serenity of the
lake, the silence of the lake, the coolness of the lake. The mirror-
like beauty of the lake is added to it. It is something more. When
God reflects in you, in your
mo chao, God becomes even more
beautiful. Something is added...
