“Abu al-Hassan (a.s.) once said to me, ‘Beware of an easy climb up that has a very deep and steep climb down.’ “The narrator has said that Abu ‘Abd Allah (a.s.) would say, ‘Do not leave the soul with its desires unguarded; its desires are to destroy it. Leaving the soul with its desires unguarded is hurting the soul, however, guarding the soul against its desires is medicine for its illness.’”
