In plain words
[...he says it, and he does it in deed as well.] And here is the verse spoken of this: 'Desire stirred in the beginning, over the face of mind — that was the first seed mind ever held. Searching within their own hearts, the seers found, by sheer reflection, the bond that ties what is to what is not.' Whatever a being desires draws near to it. He, Prajāpati, entered into austerity. And having burned through that austerity, he saw it — the king of all mantras, the Narasiṃha mantra, carried in the Anuṣṭubh metre. By that mantra alone he brought forth everything that is. That is why everything that is here is called, simply, Anuṣṭubh. Every creature is born from the Anuṣṭubh, lives by the Anuṣṭubh, and at the end goes back into the Anuṣṭubh and disappears there. And of this it is said: the Anuṣṭubh is the first, and the Anuṣṭubh is the last. Speech itself is the Anuṣṭubh — by speech alone do beings depart, by speech alone do they arise. Of every metre there is, this one — the Anuṣṭubh — stands supreme.
Close to the Sanskrit
[...] he speaks it; by action he performs it. Regarding this, this [verse] is cited: 'Desire arose in the beginning, upon the mind — that was the first seed of mind, which was. The sages, searching in the heart, found by reflection the bond of the existent in the non-existent.' Unto him comes near whatever he desires. He performed austerity. Having performed that austerity, he saw this king of mantras, the Narasiṃha [mantra] in the Anuṣṭubh metre. By that indeed he created all this, whatever there is here. Therefore they call all this, whatever there is, 'Anuṣṭubh.' From the Anuṣṭubh indeed these beings are born; born of the Anuṣṭubh, they live; into the Anuṣṭubh they depart and merge. Regarding this, there is this [further verse]: 'The Anuṣṭubh is first; the Anuṣṭubh is also the last. Speech indeed is the Anuṣṭubh; by speech alone they depart, by speech alone they arise. Supreme indeed is this among the metres — namely, the Anuṣṭubh.' (1)
