The one hundred and seventh sutta of the Majjhima Nikáya; preached to Ganaka-Moggallána. Moggallána says that the brahmanical training is a thoroughly graduated system (anupub-basikkhá anupubbakiriyá). Can the Buddha say the same of his teaching? The Buddha says he can and proceeds to explain. It is true that not all the Buddha's disciples attain to the goal, but the fault is theirs; the Buddha accepts no responsibility, he only indicates the way. M.iii.1ff.
