There, in fleshy regions, [the puncture is] the measure of a barley grain with a vrīhimukha instrument; / otherwise, the measure of half a barley grain or the measure of a grain of rice; / above bones, the measure of half a barley grain with a kuṭhārikā; / and everywhere, neither superficial nor deep, straight, unconfused, without injuring the vital spots and so on, one should swiftly drop the instrument in the middle of the vein. / From pitta arise minute, firm eruptions resembling puffed rice; / but one of such kind that is large is called gandhanāmā.
