Now one might ask, what kind of preparation is needed? The answer is: a moral preparation; but not in the sense that we understand the word "moral" in everyday life. What we understand is selfish, because we judge another according to our law instead of considering him according to his law. According to the Sufi idea moral is a different thing, especially in regard to this preparation; it is consideration of the law of friendship, of the relationship with one's elders or superiors or those who are younger or inferior. Although friendship is a simple thing to consider, it is most difficult to practice it. If we live a life of friendliness there is nothing better we can live for, and if we know the principle of friendship we do not need the moral of the world. If instead of his own advantage and rules of conduct a man considers the advantage and rules of another person, then he begins to see that person's soul, but as long as he sees the other as a separate being different from himself he will see him wrongly.
