Shoyoroku - Case 22: Ganto's Bow to the Kaatz

Ganto came to Tokusan. He straddled the threshold of the gate and asked,
  "Is this ordinary or is this holy?"
Tokusan shouted,
  "Kaatz!"
Ganto made a deep bow.
Hearing of this, Tozan said,
  "Hardly anyone but Ganto could have accepted it that way."
Ganto said,
  "Old Tozan can't tell between good and bad. At that time, I raised up with
   one hand and suppressed with the other."
