| no_author, KASSAPA-SĪHANĀDA SUTTA — Sutta 8 of the Digha Nikaya
“ It would be quite possible for a householder, or for the son of a householder, or for any one down to the slave girl who carries the water-jar, to know: “This man goes naked, or is of loose habits, or licks his fingers with his tongue,” and so on through all the items of those three lists of yours. But since, Kassapa, quite apart from these matters, quite apart from all kinds of penance, it is hard to recognise a Samaṇa, hard to recognise a Brāhmaṇa, therefore is it fitting to say: “Hard is it to know when a man is a Samaṇa, to know when a man is a Brāhmaṇa!” ”
