Then said a teacher, speak to us of Teaching.

And he said:

No mancan reveal to you aught but that
which already lies half asleep in the dawning
of your knowledge.

 The teacher who walks in the shadow of
the temple, among his followers, gives not
of his wisdom but rather of his faith and
his lovingness. 

If he is indeed wise he does not bid you
enter the house of his wisdom, but rather
leads you to the threshold of your own mind.
 
From The Prophet, Kahlil Gibran
