"The Teacher, however great, can never give his or her knowledge to the pupil; the pupil must create his or her own knowledge."
Bowl of Saki, September 19, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:
"The work of a mystical Teacher is not to teach, but to tune, to tune the pupil so that the pupil may become the instrument of God. For the mystical Teacher is not the player of the instrument; the Teacher is the tuner." from http://wahiduddin.net/mv2/X/X_2_2.htm
Some students want the Teacher to do something, to make the student "realize", to bring about Enlightenment in the student. Of course, if what the Teacher says or does, does not fit into what the student already thinks, then it is rejected. So here, Murshid says that the Teacher's work is not to give a belief to the student, only to tune. You are the instrument. What melody are you playing in the Divine symphony? What melody do you want to play?
It is when we feel “touched” by something, that the inner quality of the heart can grow and expand, deepen. Since Murshid was a highly accomplished classical Indian musician, the image of tuning was dear to him. In another place he describes how our soul is like a musical string – with one end fastened in the finite and the other end fastened in the infinite. Beautiful.
