Shoyoroku - Case 68: Kassan Brandishes the Sword

A monk asked Kassan,
  "What if one sweeps away the dust and sees Buddha?"
Kassan said,
  "You must brandish your sword. If you do not brandish your sword, the
   fisherman dwells in a nest of reeds [1]."
The monk mentioned this to Sekiso and asked him,
  "What if one sweeps away the dust and sees Buddha?"
Sekiso said,
  "He has no country. Where can one meet him?"
The monk reported this to Kassan. Kassan ascended the rostrum and said,
  "As for the facilities in the garden [2], the old monk [3] is superior to
   Sekiso, but for deep discourse expounding the true principle he is one
   hundred steps ahead of me."

[1]: That is, unable to catch a single fish.
[2]: Better teaching methods.
[3]: I.e., "I."
