Yassālayā na vijjanti, aññāya akathaṃkathī;Amatogadhamanuppattaṃ, tamahaṃ brūmi brāhmaṇaṃ.

Yassalaya na vijjanti, annaya akathamkathi; Amatogadhamanuppattam, tamaham brumi brahmanam.

He in whom there are no attachments, who through knowledge is without doubt, who has reached the deathless ground — him I call a brahmin.
