For discovery of God, simplicity is very important.  It is impossible to have a realization of God in a state of luxury. A person discovers God in a state of helplessness. Simplicity brings helplessness. Where there is luxury, there cannot be an experience of helplessness. Hazarat Umar Faruq ruled over a large empire. He used to travel on a camel. He went to Palestine on camelback. People asked him to travel on a horse instead. They brought a horse for him and made Umar mount it. The horse was very fine. But Umar dismounted it after a while.  He said sitting on the horse he felt pride enter his soul. (Futuh al-Sham, al-Waqidi, 1:231)

If there is pride, how can one discover God? If you have pride, you cannot reach God. One who wants to discover God has to decide to lead a simple life. No person can have an experience of helplessness without simplicity. If he doesn’t experience helplessness, he won't even connect with God.
