"There’s a passage where [the Buddha] contrasts his way of teaching with what he calls training in bombast. Training in bombast is where you’re taught things that are very poetic, that sound very high, very lovely, very inspiring, but no one is encouraged to ask what, precisely, they mean. After all, in bombast there really is no precise meaning. It’s all just vague, high-sounding words. But, as the Buddha said, he taught cross-questioning. Your training with him was in cross-questioning. When there was a teaching you didn’t understand, he encouraged you to ask, “What’s the meaning of this? What’s the purpose of that? How far should this word be taken?” That way, wherever there are any doubts or uncertainties, you can clear them up."
