Which states of the digestive fire does chapter 2 describe, how are they defined, and which procedures does the text pair with the disordered ones?

Detailed answer

Verse 11 asks the physician to judge whether a person's fire is balanced, irregular or weak; verse 12 says disordered fire is threefold, irregular from vāta, sharp from pitta and weak from kapha, and its footnotes give the definitions. Verse 13 pairs enema, purgation and emesis with nasal therapy with these in order, and verse 14 says balanced fire is protected by seasonal food and by enemas, purgation and emesis suited to the three periods; a footnote defines balanced fire. These are purification procedures that the text assigns to the physician.
