An epileptic, one having a string of scrofulous swellings, one who suffers from leucoderma, the backbiter, the lunatic, the blind man, and the derider of the Veda—all these should be avoided.—(161)

Medhātithi’s commentary (manubhāṣya):
The words here used signify particular diseases.

‘Bhrāmarī’—is an epileptic.

‘Gaṇḍamāti’—on whose cheeks and throat there appear swellings in the form of a string.

‘Śvitra’—is white leprosy, leucoderma.

‘Piśuna,’ ‘backbiter,’ is one who betrays other people’s secrets, and accuses them on the sly.

‘Lunatic’—whose mind is unsettled, either when there is derangement of his humours or when he is obssessed by a ghost, and he says and does things at random.

‘Blind man’—who is without eyes.

‘Derider of the Veda’—“The derider of the Veda has been already mentioned before by the term ‘brahmadviṭ’ ‘who is inimical to Brahman,’ where the term ‘brahman’ has been explained as having several meanings (signifying the Brāhmaṇa as well as the Veda).”

Not so; deriding is something totally different from being inimical; being inimical is a property of the mind, while deriding is speaking ill, of one by words expressing disregard.—(161)
