This is just what happens in the development of a saintly personality. When once the Nafs is crushed you will never find it necessary to be angry any more, though you can act the part of one who is angry and pretend to be angry. So if it is necessary to show anger this does not mean the fire of hell for you as it would be for others, for you are only using an instrument, and that instrument is not your master. In the same way you are justified in whatever course you find before you in life, as long as you really have freed yourself from control by the Nafs.
