To follow the rule of God is discipline. Shasta-God is the one who is always under his rule, who is never ruled by others at any time. Discipline is the main formula for self-peace and ultimate success in life. Supreme development is possible in life by self-discipline. Whether he becomes an Arihanta or Siddha, one who adjusts himself in his discipline or who is himself disciplined then there is no need by others to rule over him. Discipline should arise from within and should not be imposed from outside. Discipline is must in every area of life. Social, political, religious, spiritual, life principles and other disciplines are the cause of success of self and others. Discipline is like a wish fulfilling tree and success is like a creeper that climbs over it.
