I disagree. A good teacher can give you exactly what you need to move on. Thats the whole point of a teacher student relationship.
sorry couldn't resist a post here.
The teacher can only point and give advice and show you. The student must must must absolutely must, find out for him or self what it means.
A good teacher imparts the art, in such a way that self discovery is guided too, and not something that is told to you. if it is told to you then you don't "know", it is second hand knowledge, and is not truly known in your heart. FWIW
