Prasna Upanisad

The Prasna Upanisad is assigned to the Atharvaveda. The individual books are themselves called prasna, questions.

OM. Gods, may we hear good fortune with our ears!
You worthy of sacrifice, may we see good fortune with our eyes!
Having praised you with bodies strong of limb,
May we attain, life long,
what is ordained by the gods!
May Indra, of great swiftness
May Pusan, the all-knowing,
May Tarksya Aristanemi,
May Brhaspati ordain well-being for us!

OM. Peace, peace, peace.
