Lords and wealthy men, and kings especially, generally have more enemies than friends. / Hence, dispatched by them, attendants close at hand administer poison in food, drinks, and the like, / and women [do so], dispatched by their spies, out of a desire for good fortune. / Therefore, the king should retain a royal physician who is well-born, affectionate, trustworthy, orthodox, blameless in conduct, skillful, courteous, discreet, pure, unpretentious, unwearied, free from vices, humble, unangered, not rash, adept at understanding the meaning of speech, thoroughly learned in the eight branches of Āyurveda according to the traditional teaching, well-provided with security, equipped with antidotes and other formulations at hand, and knowledgeable in suitability. / Him he should honor with wealth and respect at the proper time, as a pupil honors a teacher, as a son honors a father. / Even unpalatable words of his he should regard as proper counsel. / For even a noble lordly elephant, if unrestrained by a goad, is not praised by the people. / Therefore, regarding food and conduct, he should place himself under his authority. / Indeed, even life that has been acquired stands by itself only through the power of proper measures.
Therein, whatever doṣa—one or more—is in excess during semen, menstrual fluid, uterus, [conception] time, and the mother's diet and conduct, by that, until death, one's innate constitution is born, just as a worm born in a poisonous creeper is born from its poison, or as a poisonous creature like a scorpion or a venomous serpent is born with its own poison.
Fasting [is prescribed] first, except in vāta; there one should employ emesis, / through asceticism, good conduct, mental composure, knowledge, generosity, compassion, and the like.
