HYMN XI

An epithalamian charm to ensure the birth of a boy

1Asvattha on the Sami-tree. There a male birth is certified.
  There is the finding of a son: this bring we to the women-folk.
2The father sows the genial seed, the woman tends and fosters it.
  This is the finding of a son: thus hath Prajāpati declared.
3Prajāpati, Anumati, Sinivāli have ordered it.
  Elsewhere may he effect the birth of maids, but here prepare a
   boy.
