The Upanishads, Part 1 (SBE01), by Max Müller, , at sacred-texts.com
1. He recites the Vasa hymn 1, wishing, May everything be in my power.
2. They (its verses) are twenty-one 2, for twenty-one are the parts (the lungs, spleen, &c.) in the belly.
3. Then the Ekavimsa is verily the support of all Stomas, and the belly the support of all food.
4. They consist of different metres. Verily, the intestines are confused, some small, some large.
5. He recites them with the pranava 3, according to the metre 4, and according to rule 5. Verily, the intestines are according to rule, as it were; some shorter, some longer.
6. Next comes the Sûdadohas verse. Sûdadohas verily is breath. He joins the joints; with breath.
7. After having recited that verse twelve times he
leaves it off there. These prânas are verily twelvefold, seven in the head, two on the breast, three below. In these twelve places the prânas are contained, there they are perfect. Therefore he leaves it off there 1.
8. The hymn indrâgnî yuvam su nah (Rv. VIII, 40) forms the two thighs (of the bird) belonging to Indra and Agni, the two supports with broad bones.
9. These (verses) consist of six feet, so that they may stand firm. Man stands firm on two feet, animals on four. He thus places man (the sacrificer), standing on two feet, among four-footed cattle.
10. The second verse has seven feet, and he makes it into a Gâyatrî and Anushtubh. Gâyatrî is Brahman, Anushtubh is speech; and he thus puts together speech with Brahman.
11. He recites a Trishtubh at the end. Trishtubh is strength, and thus does he come round animals by strength. Therefore animals come near where there is strength (of command, &c.); they come to be roused and to rise up, (they obey the commands of a strong shepherd.)
193:1 Having recited the verses which form the body, neck, head, wings, and tail of the bird, also the food intended for the bird, he now describes the Vasa hymn, i.e. the hymn composed by Vasa, Rv. VIII, 46. That hymn takes the place of the stomach which receives the food intended for the bird. Cf. Ait. Âr. V, 2, 5. In I, 5, 2, 4 it is called a Nivid.
193:2 Verses 1-20 of the Vasa hymn, and one Sûdadohas.
193:3 Pranâvam means 'with pranava,' i.e. inserting Om in the proper places.
193:4 According as the metres of the different verses are fixed by Saunaka, Ait. Âr. V, 2, 5, who says that verse 15 is Dvipadâ, and that the last four words, nûnam atha, form an Ekapadâ.
193:5 According to rule, i.e. so that they should come right as Âsvalâyana has prescribed the recitation of Dvipadâ and Ekapadâ verses. In a Dvipadâ there should be a stop after the first foot, and Om at the end o f the second. Ira an Ekapadâ there should be Om at the beginning and at the end.
