HYMN CXL

A blessing on a child's first two teeth

1Two tigers have grown up who long to eat the mother and the
   sire:
  Soothe, Brāhmanaspati, and thou, O Jātavedas, both these
   teeth.
2Let rice and barley be your food, eat also beans and sesamum.
  This is the share allotted you, to be your portion, ye two Teeth.
  Harm not your mother and your sire.
3Both fellow teeth have been invoked, gentle and bringing happi-
   ness.
  Else whither let the fierceness of your nature turn away, O
  Teeth! Harm not your mother or your sire.
