HYMN CXIV

A prayer for pardon of faults and errors in sacrificing

1Whatever God-provoking wrong we priests have done, O
  Deities.
  Therefrom do ye deliver us, Ādityas! by the right of Law.
2Here set us free, O holy ones, Ādityas, by the right of Law.
  When striving, bringing sacrifice, we failed to offer it aright.
3With ladle full of fatness we, worshippers, pouring holy oil,
  Striving, have failed, O all ye Gods, against our will, to offer it.
