The Code of Menu lays it down that diseases are the consequences of sinful acts in previous states of existence. “Men of evil manners receive an alteration of form, some through evil (deeds) committed (by them) in this life, some also through (acts) formerly committed. A thief of gold (receives) the disease of bad nails; a drinker of intoxicating liquor (the disease of) black teeth; a slayer of a Brahman, consumption; he who violates the couch of the Guru, a skin disease; a slanderer, a foul-smelling nose; a false informer, a foul-smelling mouth; a stealer of grain, the loss of a limb, and one who mixes (grain) a superfluity (of limbs); one who takes food, dyspepsia; a thief of the voice, dumbness; a thief of clothes, leprosy; a horse-thief, lameness; a stealer of a lamp would (in the next birth) become blind; an extinguisher (of a lamp), one-eyed; by (committing) injury (one would get) a condition of disease; by not (committing) injury, the condition of not being diseased. Thus, according to the difference in their acts, (men who are) blamed by the good are born dull, dumb, blind, and deformed in appearance. Regularly, then, penance should be practised for purification, since those whose sins have not (thus) been done away with are (re)born with (these) disgraceful marks attached.”[234] Physicians are referred to several times in the _Ordinances of Menu_. In Lect. iv. 179 we are advised that “we should never have a dispute with a physician.” We are to avoid eating the “food of a physician and hunter, if a cruel man,” etc. (Lect. iv. 212). “The food of a physician is pus” (_Ibid._ 220). In Lect. ix. 284, “A fine (is set) for all physicians treating (a case) incorrectly: in (the case of creatures) not human (this is) the first, but in (the case of) human beings the medium (fine).”[235] The Brahmans believed there was a remedy for every disease, in consequence of which they made a very careful examination of the vegetable kingdom, and so discovered a great number of medicines. If a medicine were efficacious in curing the patient, they invariably supposed it was due to the sanctity of the individual, and the divine pleasure which endowed him with it. It is therefore exceedingly difficult to obtain information, as it is believed that the medicine would lose its effect if the secret of the cure were divulged to others. From these selfish motives, the knowledge of the properties of many valuable remedies have been lost. Dr. Wise says, according to the Brahmans, there are nine secrets which should not be revealed to any one: these are the age of a person; his wealth; family occurrences; his bad actions, or those which reflect shame or dishonour upon him; his relations with his wife; his prayers to his tutelar gods; his charities; and the virtues of nostrums, the ingredients of which are known to him.
