Chapter 4, Part 3B - Lieh Tzu

Wên Chih replied by asking Lung Shu to stand with his back to the light, while he himself faced the light and looked at him intently. 'Ah!' said he after a while, 'I see that a good square inch of your heart is hollow. You are within an ace of being a true sage. Six of the orifices in your heart are open and clear, and only the seventh is blocked up.

This, however, is doubtless due to the fact that you are mistaking for a disease that which is really divine enlightenment. It is a case in which my shallow art is of no avail.'
