Shoyoroku - Case 37: Isan's "Karma-Consciousness"

Isan asked Kyozan,
  "Suppose a man asks you, saying, 'All living beings are tossed in a vast
   karma-consciousness, and have no foundation to rely upon.' How would
   you check him?"
Kyozan said, 
  "If such a monk appears, I call out to him, 'Mr. So-and-so!' When he turns
   his head, instantly I say, 'What is this?' If he hesitates, then I say to
   him, 'Not only is there a vast karma-consciousness, but also there is no
   foundation to rely upon.'"
Isan said,
  "Good."
