Someone asked, “What is my heart-mind?”
  Changsha replied, “All the worlds in the universe are your heart-mind.”
  “If that’s so, then there’s really no particular place for my body to be.”
  “That’s exactly the place for your body to be,” said Changsha.
  “Where is that?”
  “The great ocean, vast and deep.”
  “I don’t understand.”
  “Dragons and fish play freely, leaping and diving.”
