Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
At the moment of letting the seed fall the husband recites a mantra; he gives that mantra: "yathāgninā". Bhūḥ: the earth. Dyauḥ: heaven. "Vajradhāriṇā": by Indra, who holds the thunderbolt. [The mantra: "As the earth is pregnant with fire, as heaven with the wielder of the thunderbolt, as the quarters with the wind, so be you pregnant."]
