HYMN CXIII

A woman's incantation against a rival

1Rough Plant, thou rough rude parasite, cut thou that man, O
  Rough and Rude,
  That thou mayst hinder from his act that man in all his manly
   strength.
2Thou, rugged Plant, art rude and rough, Vishā, Vishātaki art
   thou.
  That thou mayest be cast off by him, as by a bull a barren cow.
