Application
Ch'eng-t'ien was asked, "How should I apply my mind twenty-four hours a day?"
He replied, "When chickens are cold, the roost in trees; when ducks are cold, the plunge into water."
The questioner said, "Then i don't need cultivated realization, and won't pursue Buddhahood or Zen mastery."
Ch'eng-t'ien responded, "You've saved half my effort."
