11.3

Filling to one-third or filling to half is prescribed for heavy foods;

for light foods as well, not over-satiation.

For light foods, abounding in the qualities of wind and fire, kindle the digestive fire because of their similar qualities, and [even] if taken without rule produce little fault;

others, however, abounding in the qualities of earth and water, are opposite due to dissimilarity, except through the strength of exercise and the digestive fire.

Lack of measure, moreover, is the deficiency and excess of eating.

Among them, eating in deficient measure causes damage to strength, complexion, nourishment, mind, intellect, and the sense organs, causes constipation, is non-aphrodisiac, unwholesome for the vital essence, destroys the bodily essence, produces misfortune, and is the abode of eighty disorders of vāta.

Excessive measure, on the other hand, they say, provokes all the doṣas.

For, being oppressed by it, vāta and the others, simultaneously provoked and stationed in one part of the belly, pervade that very undigested [food], making it sluggish, and produce alasaka;

or, driving it forth suddenly through the lower and upper paths, [they produce] viṣūcikā.

Accompanied by delirium, giddiness, and dyspnea, wasted, swollen, with destroyed digestive fire;

that swelling which is external or internal, deeply rooted, and exceedingly painful;

for, when his channels are cleared and the remainder of the doṣa is driven forth,

it is easy to effect binding with digestives or with an astringent;

the eyelid-junction, the white, the black, the pupil, or the entire eye.
