Lohicca Sutta 17.7

17.7

“idaṃ vo hitāya, idaṃ vo sukhāyā”ti.

‘In the second place, Lohicca, there is a sort of teacher who has not himself attained to that aim of Samaṇaship for the sake of which he left his home and adopted the homeless life. Without having himself attained to it he teaches a doctrine to his hearers, saying: “This is good for you; that will make you happy.” And to him his disciples listen; they give ear to his words; they become stedfast in heart by their understanding what is said; and they go not their own way, apart from the teaching of the master. Such a teacher may be rebuked, setting out these facts and adding: “You are like a man who, neglecting his own field, should take thought to weed out his neighbour’s field. Like that, do I say, is this lust of yours (to go on teaching others when you have not taught yourself). For what, then, can one man do for another?”
‘This, Lohicca, is the second sort of teacher in the world worthy of blame. And whosoever should blame such a one, his rebuke would be justified, in accord with the facts and the truth, not improper.
