I can teach you, you can teach me
I can give knowledge to you and you can give knowledge to me. But we can't give each other wisdom. That comes from within each person. If you heave trivial knowledge overboard and digest beneficial knowledge, if you do this by staring into the sacred fire, then wisdom can begin to illuminate. The fire of wisdom will burn away all obstacles, errors, obscurations, and delusions. And manzanita burns the hottest.
