The sons, however, did not understand, and finally called in three physicians, Dr Chiao, Dr Yü and Dr Lu. They all diagnosed his complaint; and Dr Chiao delivered his opinion first: 'The hot and cold elements of your body,' he said to Chi Liang, 'are not in harmonious accord, and the impermeable and infundibular parts are mutually disproportionate. The origin of your malady is traceable to disordered appetites, and to the dissipation of your vital essence through worry and care. Neither God nor devil is to blame. Although the illness is grave, it is amenable to treatment.'Go here to read the introductory post to the chapters of the Book of Lieh Tzu.
Chi Liang said: 'You are only one of the common ruck,' and speedily got rid of him.
Then Dr Yü came forward and said: 'You were born with too little nervous force, and were too freely fed with mother's milk. Your illness is not one that has developed in a matter of twenty-four hours; the causes which have led up to it are of gradual growth. It is incurable.'
Chi Liang replied: 'You are a good doctor,' and told them to give him some food.'
Lastly, Dr Lu said: 'Your illness is attributable neither to God, nor to man, nor to the agency of spirits. It was already fore-ordained in the mind of Providence when you were endowed with this bodily form at birth. What possible good can herbs and drugs do you?
'You are a heaven-born physician indeed!' cried Chi Liang; and he sent him away laden with presents.
Not long after, his illness disappeared of itself.
