HYMN XXVII

A charm against an opponent in debate

1Let not the enemy win the cause! Strong and predominant art
   thou.
  Refute mine adversary's speech. Render them dull and flat, O
  Plant.
2The strong-winged bird discovered thee, the boar unearthed thee
   with his snout.
  Refute mine adversary's speech. Render them dull and flat, O
  Plant.
3Yea, Indra laid thee on his arm, to cast the Asuras to the
   ground.
  Refute mine adversary's speech. Render them dull and flat, O
  Plant.
4Indra devoured the Pātā plant that he might lay the Asuras
   low.
  Refute mine adversary's speech! Render them dull and flat, O
  Plant. p. a54
5With this I overcome my foes as Indra overcame the wolves.
  Refute mine adversary's speech! Render them dull and flat, O
  Plant.
6O Rudra, Lord of Healing Balms, dark-crested, skilful in thy
   work!—
  Refute mine adversary's speech. Render them dull and flat, O
  Plant.
7Indra, defeat the speech of him who meets us with hostility.
  Comfort us with thy power and might. Make me superior in
   debate.
