hrasvaṃ liṅgaṃ mārdavaṃ cāpi vīndra tallakṣaṇaṃ pañcaviṃśaṃ vadanti /
samau ca pādau kaṭijānu corū ṣaḍviṃśamāhuśca same ca jaṅghe //

A short, soft organ, O king of birds, they declare as the twenty-fifth mark. / Symmetrical feet, waist, knees, and thighs, and symmetrical shanks they call the twenty-sixth.
