'And he who offers the fifth oblation, should offer it to Udâna (out-breathing), saying Svâhâ. Then Udâna is satisfied,

'If Udâna is satisfied, Vâyu (air) is satisfied, if Vâyu is satisfied, ether is satisfied, if ether is satisfied, whatever is under Vâyu, and under the ether is satisfied. And through their satisfaction he (the sacrificer or eater) himself is satisfied with offspring, cattle, health, brightness, and Vedic splendour.
