金光明經文句 6.16

6.16

子請為三：一見人遇病、二思惟、三正問。問為四：初一偈問四大增損、二問飲食犯觸、三問治病醫方、四問病動時節。身火不滅者，食飽熱病慚息，食消熱復更生，故言身火不滅也。水過肺病者，水多則損肺，即是痰病也。

The son's request is divided into three: first, seeing people contract disease; second, contemplation; third, the actual question. The question is divided into four: the first verse asks about the increase and decrease of the four great elements; the second asks about transgressions and infractions regarding food and drink; the third asks about medical prescriptions for treating disease; the fourth asks about the seasons when diseases arise. 'The fire of the body is not extinguished': when one eats to fullness, the feverish disease temporarily subsides; when the food is digested, the heat arises again; hence it says 'the fire of the body is not extinguished'. 'Water transgressing [causes] lung disease': when water is excessive, it harms the lungs, which is phlegm disease.
