Buddha didn't learn the things he knew. He came to a realisation. When it comes to teaching, we aren't teaching, we're providing the environment for students to have a realisation. That is one thing that Master Hoshino got right. Yamabushi are not the teachers, Yamabushi simply set up the environment for our students, our fellow Yamabushi, to have a realisation. Nature is the teacher.

But when it comes to education in school, it is very much the same. What it means to set up the environment for realisation differs between teachers, but that's what they should be doing (it isn't always the case that they are).

In the same manner, we can set up ourselves to have a realisation too. All it takes is making the right environment.
