3.29.2

Ye hi keci, bhikkhave, samaṇā vā brāhmaṇā vā pubbantakappikā vā aparantakappikā vā pubbantāparantakappikā vā pubbantāparantānudiṭṭhino pubbantāparantaṃ ārabbha anekavihitāni adhimuttipadāni abhivadanti, sabbe te imeheva dvāsaṭṭhiyā vatthūhi, etesaṃ vā aññatarena; natthi ito bahiddhā.

Any ascetics and brahmins who speculate and theorize about the first beginning or the final end do so on one or other of these sixty-two grounds. Outside of this there is none.
