v2.c77.25

An eye should be of the form of a bow or (like) the abdomen of a fish, or like a petal of the blue lotus (utpala), or of the white lotus (padma), a fifth, (oh) great king, is said to be of the form of a grindstone. An eye of the form of a bow should belong to women (in general). An eye of 4 *yavas* (in width) is called by the naine of fish-abdomen. A blue-lotus-petal-eye is traditionally said to be 6 *yavas* and a red- or white-lotus-petal eye is 9 *yavas* in measurement. So an eye of the shape of a grind stone should be 10 *yavas*. The measure of a *yava* should be calculated proportionate to the ineasurement of an *angula*, which has its own standard.
