पिता माता प्रजैत एव मन एव पितावाङ्माता प्राणः प्रजा ॥ ७ ॥
In plain words
Father, mother, and offspring—understood thus: the mind is truly the father, speech is the mother, and the vital breath is the offspring.
Close to the Sanskrit
Father, mother, progeny—thus indeed: the mind indeed is the father, speech is the mother, prana is the progeny.
