Master Shui Lao asked Ma Tsu, "What is the
true meaning of the coming from the West?"

Ma Tsu then knocked him down with a kick to
the chest: Shui Lao was greatly enlightened. He
got up, clapping his hands and laughing loudly,
and said, "How extraordinary! How wonderful!
Instantly, on the tip of a hair, I have understood
the root source of myriad states of
concentration, and countless subtle meanings."
Then he bowed and withdrew.

Afterwards he would tell the assembly, "From the
time I took Ma Tsu's kick, up until now, I haven't
stopped laughing."
