'Those his well-like milking ones '--a well (sûda) means water, and milking means food;--'the speckled ones mix the Soma,'--the speckled (cow) means food;--'at the birth of the gods,'--the birth of the gods is the year;--'the tribes,' the tribes (vis), doubtless, are the sacrifice, for all beings are ranged (vishta) under the sacrifice;--'in the three spheres of the heavens,'--the three spheres of the heavens, doubtless, are the (three) pressings (of Soma): he thus means the pressings. With an anushtubh verse (he performs this rite), for the Anushtubh is speech, and speech (includes) all vital airs; and by means of speech, that is vital air, he thus makes these two (bricks) continuous, and joins them together. This same Sûdadohas, whilst being a single (verse), extends over all the bricks, whence--the Sûdadohas being the vital air--this vital air, whilst being one only, extends over all the limbs, over the whole body.
