Self-control is the most necessary thing to be learned; a person may have great spirituality, illumination and piety, but in the absence of self-control this is nothing. Self-control also is the only way of happiness and peace. Often we hear or read that persons of great repute in the world for their spirituality and mysticism do something that astonishes us very much, or make a quite childish mistake. It is want of self-control that makes them commit a mistake, against which they themselves have spoken and written many times.
