The Compendium of Bheḷa 6.11

The fire [is the source of] lifespan of men; the vital breaths are established in it; / strength, health, lifespan, pleasure, and pain are dependent on it.

For when the fire is extinguished, one dies, and when warmth is present, one lives; / therefore one should know that the vital breaths and life of embodied beings are rooted in fire.

That fire extends downward the properly consumed food for the sake of chyle; / by that, a man gains sensory strength, nourishment, and complexion.

Fire digests in four ways: balanced, sharp, and likewise sluggish, / and irregular; but among these, that fire which is balanced is praised.

In those who indulge in heavy and dry food and day-sleep constantly, / or do not sleep properly at night, and likewise in those who suppress natural urges;

in those who eat when food is undigested, who undergo purgation with excessive unction, / through fever, addiction to liquor, and likewise through indulging in unwholesome things;

in those constant in sweets and milk, and likewise sporting in water; / through indulgence in flour-dishes, curd, vegetables, and unwholesome foods;

by such things excessively indulged in, a creature's digestive tract is vitiated. / Sluggish, sharp, or very irregular—it is provoked in three ways.

Likewise diseases arise in men born of digestive disorders: / fever, cough, jaundice, swelling, cutting pain in the rectum,

anorexia, indigestion, abdominal lumps, piles, anal fistula, / diarrhea, dermatosis, colicky pains, alasaka, dizziness—

these and other diseases it generates in one who eats immoderately; / the vitiated digestive tract of a creature, full of āma, even kills through diseases.

For in one whose internal fire is overwhelmed by phlegm because he eats sweets, / the food is not digested in time: he is known as one with sluggish fire.

When his fire is sluggish due to phlegm, food eaten is not quickly digested; / vitiated by heavy meals, it becomes still more sluggish.

With such a nature and increased, when phlegm subsides in him, / that is spoken of as the digestive disorder named irregular.

In one whose fire is violently provoked in the body due to depletion of soma, / it digests meal after meal, yet does not contribute to complexion and strength;

and after every meal hunger arises in him and he is not nourished; / one should know that as excessive fire, and it is considered exceedingly difficult [to endure].

Thus this threefold disease residing in the digestive tract has been declared by me; / learn from me in detail its treatment:

One should drink Dhānvantara ghee or Prājāpatya [ghee]; / then one should administer emesis to him, and after that, purgation.

Or he should drink the graduated pippalī regimen, or alkali-antidotes, / and he should drink buttermilk for a month, or gaṇḍīrāriṣṭa,

and one should drink Dādhika ghee, or oil of śirīṣa, / or Mahāpañcagavya […] // Chapter Twelve // […]
