There is a story of Umar, the well-known khalif of Arabia. Someone who wanted to harm Umar was looking for him, and he heard that Umar did not live in palaces - although he was a king - but that he spent most of his time with nature. This man was very glad to think that now he would have every opportunity to accomplish his objective. As he approached the place where Umar was sitting, the nearer he came, the more his attitude changed, until in the end he dropped the dagger which was in his hand, and said: "I cannot harm you. Tell me, what is the power in you that keeps me from accomplishing the objective which I came to carry out?" Umar answered: "My at-one-ment with God."
