HYMN XXI

A charm to strengthen hair and promote its growth

1Of all the three terrestrial realms the ground is verily the best.
  I from the skin that covers these gather a healing medicine.
2Thou art the best of medicines, most excellent of Plants art
   thou,
  As Soma 'mid the wandering stars, as Varuna among the Gods.
3Endowed with wealth, denying not, give freely fain to give your
   gifts!
  Ye stay the hair from falling off: ye strengthen and increase its
   growth.
