I become more than ever convinced that it was not the sword that won a place for Islam in those days. It was the rigid simplicity, the utter self-effacement of Hussein, the scrupulous regard for pledges, his intense devotion to his friends and followers and his intrepidity, his fearlessness, his absolute trust in God and in his own mission. These and not the sword carried everything before them and surmounted every obstacle.
A theory is the more impressive the greater is the simplicity of its premises, the more different are the kinds of things it relates and the more extended the range of its applicability.
Elegance is achieved when all that is superfluous has been discarded and the human being discovers simplicity and concentration: the simpler and more sober the posture, the more beautiful it will be.
