HYMN LII

1We compass thee like waters, we whose grass is trimmed and
  Soma pressed.
  Here where the filter pours its stream thy worshipper round
   thee, O Vritra-slayer, sit.
2Men, Vasu! by the Soma, with lauds call thee to the foremost
   place.
  When comest thou athirst unto the juice as home, O Indra, like
   a bellowing bull?
