Therefore study and practice of breath have been kept a mystery - not in order to monopolize them for a certain school, for no true mystic can be without generosity. The first sign of a mystic is that he is ready to give to everyone. The first and last lesson is to give - to give to the end, to give everything one possesses. There is no end to the giving of the mystic, as there is no end to the inspiration he receives. If breath has been made a mystery, it is only as one would keep an object of glass from a little child, fearing that he might break it, hurting himself and others.
