The formless, what is that? As a pianist, I can best begin to understand through the study of piano music: notes on a page, each one to be taken hold of by the fingers and made to sing. One learns to listen, to seek the composer's intention, to try to recapture the tempo; to give attention to every note, however small, and to love each silence... Music is a transmission from one person to another, a deepening of understanding, and an awakening to the sense of beauty and order which lives deep inside us.
If we will only learn silence, we will learn two things: to pray and to be humble. You cannot love unless you have humility, and you cannot be humble if you do not love. From the silence of the heart God speaks.
