But if the will is under the control of anger, passion, etc, so that they manifest regardless of wisdom, and come into play at their own time (which depends on the person's habit) then a person will get cross every day! He gets cross because he has made it a habit, and his will has submitted. If this happens every day for eight days, it will happen on the ninth, or else perhaps he may fall ill. The power which should be obedient to the will controls it instead, and so the will works without wisdom in spite of the fact that wisdom is the only reliable power which God has given man.
