Thus ease comes from considering this world to be insignificant, giving up one's enjoyment of it, and removing the impurity of what is forbidden or doubtful. A person closes the door of pride on himself once he recognizes this; he flees from wrong actions and opens the door of humility, regret and modesty. He strives to carry out Allah swt's commands and to avoid His prohibitions, seeking a good end and excellent proximity to Allah swt. He locks himself in the prison of fear, steadfastness, and the restraint of his appetites until he reaches the safety of Allah swt in the world to come and tastes the food of His good pleasure. If he intends that, everything else means nothing to him.
