The Long Āgama Sūtra 26.23

26.23

佛言：「若彼三明婆羅門無有一見梵天者，若三明婆羅門先師無有見梵天者，又諸舊大仙三明婆羅門阿咤摩等亦不見梵天者，當知三明婆羅門所說非實。」

The Buddha said, “If not one of the priests who possess the three insights have seen Brahmā’s Heaven, none of the previous teachers of the priests who possess the three Vedas have seen Brahmā’s Heaven, and even the great sages of antiquity like the priest Aṣṭaka didn’t see Brahmā’s Heaven, we should know that the teachings of the priests who possess the three Vedas are untrue.”
