If the words are good and true,
it’s as if the centre of all things
fires and fills; informs the heart;
the heart, the chest and lungs;
the lungs, the unhesitating throat;
space fills the head and voice:

and then, no longer pupil,
but the teacher of the world;
hearing from the centre of that sound
that sound itself may bring about all things.

Michael Shepherd
