God gave to each soul a purpose. This purpose is to walk the straight path. Blessed are those who accept their purpose. For purpose endows the mind with strength. It feeds determination and acts as a support for the will when the will falters. It is a barrier against fear when fear tempts the mind to vice. It is the foundation of virtuous action.
