Therefore the seventeen-versed hymn is the breast. (12) The twenty-one-versed hymn-form (*ekaviṃśa*) is the abdominal portion (*udara*) of the spine. For within the abdomen there are twenty transverse processes (*kuntāpa*), and the abdominal portion of the spine is the twenty-first. Therefore the twenty-one-versed hymn is the abdominal portion of the spine. (13) The thrice-nine-versed (or 27-versed) hymn-form (*triṇava*) is the two sides (*pārśva*). There are thirteen ribs (*parśu*) on the one side, and thirteen on the other; and the two sides make up the thrice-ninth (or 27th). Therefore the thrice-ninth hymn is the two sides. (14) The thirty-three-versed hymn-form (*trayastriṃśa*) is the thoracic portion (*anūka*) of the spine; for there are thirty-two transverse processes (*karūkara*) in it, and the thoracic portion of the spine is the thirty-third. Therefore the thirty-three-versed hymn is the thoracic portion of the spine.' (Vol. v, pp. 163-5.)
