Dhammapada · 26.13

Paṃsukūladharaṃ jantuṃ, kisaṃ dhamanisanthataṃ;Ekaṃ vanasmiṃ jhāyantaṃ, tamahaṃ brūmi brāhmaṇaṃ.

Pamsukuladharam jantum, kisam dhamanisanthatam; Ekam vanasmim jhayantam, tamaham brumi brahmanam.

The one clothed in cast-off rags, lean, with veins showing on his body, who meditates alone in the forest — him I call a brahmin.
