"O disciple, listen to another statement from me, and think about it to find salvation. If you were notified that the ruler would be coming to you on a visit in a week's time, I know that during this period you would occupied with nothing but putting in order what you knew his glance would fall on of your clothing, your person, house, furnishings and so on. Now think what it is I am hinting at, for you are intelligent. A single word is enough for someone clever." --- Al-Ghazali, Letter to a Disciple
