CHAPTER 71
--------Lao Zi
  To know when one does not know is best.
To think one knows when one does not know is a dire disease.
Only he who recognizes this disease as a disease.
Can cure himself of the disease.
The sage's way of curing disease
Also consists in making people recognize their diseases as diseases and thus ceasing to be diseased.
