6 As spokes in the hub of a wheel, all are fixed in prana, including the Rig Veda, the Yajur Veda, the Sama Veda, the kshattriyas and the brahmins.

Sri Shankara’s Commentary (Bhashya) translated by S. Sitarama Sastri
As spokes in the nave of a wheel, all from sraddhâ (faith) down to name is centred in Prâna, while they endure; so also Rik, Yajur and Sâma Vêdâs, the three kinds of mantras, and what is accomplished by them, i.e., the sacrifice, the Kshatriyas, pro tectors of all and the Brahmins competent to perform sacrifices and other karma. Prâna is all this.
