Note 310:

Karṇa Vīr used five different mantars to treat headaches. He made the distinction between those to treat a full head or a half-head headache, although the appropriate mantars, š1 and š2, are quite similar. The third is a dialogic text, a conversation with a female from the iron working caste, who describes that her husband has gone to chop charcoal, with which he will forge a knife to cut thatching grass with which to plait a broom that will brush the headache away. The final two resemble Gumān's "footless" mantars against headaches, except that here, two sisters are the musicians who produce the headache.There are some discrepancies in this set that I have been unable to resolve. For example, Karṇa Vīr approved both "māṭhī" in the first one and "māthi" in the second and fourth, "matiyā" in the first, but "matijā" in the fourth.
