Shoyoroku - Case 77: Kyozan: As His Profession Requires

A monk asked Kyozan,
  "Your Reverence, do you know letters or not?"
Kyozan said,
  "According to my capacity."
The monk immediately turned around once clockwise and said,
  "What letter is this?"
Kyozan drew the ideograph for "10" [ + ] in the earth. The monk turned
himself around once counter-clockwise and said,
  "What letter is that?"
Kyozan modified the sign" + " into a swastika [1]. The monk drew a circle in
the air and lifted his two palms like Asura [2] vigorously holding the sun
and moon and said, 
  "What letter is that?"
Kyozan immediately drew a circle enclosing the swastika. The monk at once
represented the vigor of a Rucika [3]. Kyozan said,
  "Good, good. Keep it with care."

[1]: Manji in Japanese; a symbol of Buddhism.
[2]: Originally a Hindu deity, here one of the eight supernatural protectors
     of Buddhist Way.
[3]: The buddha Rucika wailed at his fate at first because he was the last of
     the thousand buddhas in this cosmic period. But then he made up his mind
     to be the energetic protector of the Dharma for all other buddhas. Two
     powerful figures of this buddha are seen at the entrance gate of many
     temples in Japan (named Nio).
