HYMN CI

A charm to promote virile vigour (Appendix)

1Taurum age, palpita, incresce et teipsum extende: per totum
   membrum increscat penis: hoc tu caede feminam.
2Quo debilem stimulant, quo aegrum excitant (homines), hoc, O
  Brahmanaspatis, hujus penem in arcus modum extende.
3Velut nervum in arcu ego tuum fascinum extendo. Aggredere
  (mulierem) semper indefessus velut cervus damam.
