HYMN XVIII

A prayer for rain

1Burst open, Prithvi, and cleave asunder this celestial cloud.
  Untie, O Dhātar—for thou canst—the bottle of the breast of
   heaven.
2Let not the Sun's heat burn, nor cold destroy her. Let Earth
   with all her quickening drops burst open.
  Even for her the waters flow, and fatness: where Soma is even
   there is bliss for ever.
