A true spiritual teacher does not have anything to teach in the conventional sense of the word. Does not have anything to give or add to you such as new information, beliefs or rules of conduct.
The only function of such a teacher is to help you remove that which separates you from the truth of who you already are and what you already know, in the depth of your being.
The spiritual teacher is there to uncover and reveal to you that dimension of inner depths that is also peace.
