Tevijjasutta 14.2

14.2

Natthi koci tevijjānaṃ brāhmaṇānaṃ ekācariyopi, yena brahmā sakkhidiṭṭho.

'Then you say, Vâsettha [that not one of the Brâhmans, or of their teachers, or of their pupils, even up to the seventh generation, has ever seen Brahmâ face to face. And that even the Rishis of
old, the authors and utterers of the verses, of the ancient form of words which the Brâhmans of to-day so carefully intone and recite precisely as they have been handed down--even they did not pretend to know or to have seen where or whence or whither Brahmâ is]. So that the Brâhmans versed in the Three Vedas have forsooth said thus: "What we know not, what we have not seen, to a state of union with that we can show the way, and can say: 'This is the straight path, this is the direct way which leads him, who acts according to it, into a state of union with Brahmâ!'"
'Now what think you, Vâsettha? Does it not follow, this being so, that the talk of the Brâhmans, versed though they be in the Three Vedas, is foolish talk?'
'In sooth, Gotama, that being so, it follows that the talk of the Brâhmans versed in the Three Vedas is foolish talk!'
