Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

First of all a mouth appeared in Him, and then came forth the organ of speech, and with it the god of fire, the deity who presides over that organ. Then a pair of nostrils appeared, and in them appeared the olfactory sense, as well as prana, the vital air.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

With the manifestation of speech, fire also became manifested, and with the manifestation of nostrils the vital air, the breathing process and the sense of smell also became manifested.
