2. The sound ū is the sun, [for people sing of the sun when it is up (ū-rdhvam)].

The sound e is the Invocation, [for people call with 'Come! (e-hi)'].

The sound au-ho-i is the Viśvadeva gods, [for this interjectional trill occurs in the Sāman to the Viśvadeva gods].

The sound hiṅ is Prajāpati, [for Prajāpati is undefined, and the sound hiṅ also is indistinct].

svara (sound) is breath, [for that is the source of sound].

yā is food, [for everything here moves (yati) through the help of food].

vāc is Virāj, [for this interjectional trill occurs in the Sāman to Virāj].
