अथ प्राणमत्यवहत् ; स यदा मृत्युमत्यमुच्यत स वायुरभवत् ; सोऽयं वायुः परेण मृत्युमतिक्रान्तः पवते ॥ १३ ॥
In plain words
Then the vital force carried the organ of smell beyond death. When it was freed from death, it became Wind. This Wind, having transcended death, now blows in its pure cosmic state.
Close to the Sanskrit
Then it carried the breath beyond; he, when he was freed having crossed over death, he became wind; that this wind, transcended beyond death, blows.
