Shoyoroku - Case 12: Jizo Plants the Rice Field

Jizo asked Shuzanshu,
  "Where have you come from?"
Shuzanshu said,
  "I have come from the South."
Jizo said,
  "How is Buddhism in the South these days?"
Shuzanshu said,
  "There is much lively discussion."
Jizo said,
  "How could that match with our planting the rice field here and making
   rice-balls to eat?"
Shuzanshu said,
  "How could you then save the beings of the Three Worlds?"
Jizo said,
  "What do you call 'the Three Worlds'?"
