"Therefore they say, "the breath is Vayu (God of the wind), seed is breath; seed comes into being first when man comes into existence." In that he recites a triplet to Vishnu, thus he makes his breath perfect. A triplet to Indra and Vayu he recites. Where there is expiration, there is inspiration; in that he recites a triplet to Indra and Vayu, thus his expiration and inspiration he makes perfect (AB 111.2)."
