A Teacher Should Be Able to Answer All Questions

I studied and practiced for 20 years before I met Francis. He said a teacher should be able to answer all questions. And he gave an analogy that helped me to understand what he meant. It's not that one who speaks of these matters has a storehouse of knowledge. It's that there's no knowledge. But every question is like a bucket that is dipped in the ocean. And it is the teacher's... The art of the teacher is to tailor the understanding. Formless understanding has no form.
