什麼是蘇菲 (Sufi)？嚴格來說，每一個探尋那究竟真理的人，都是一位蘇菲，不管他是否如此自稱。……
所有的信仰 (beliefs) 都只是那個「看見」(vision) 的清晰度的差別而已。所有一切都是那唯一的真理之海的一部分。當一個人對此理解得越多，他就越容易去看到所有信仰之間的真實的關係，他對那一個偉大的真實之海的視野也會更加地廣闊。
所謂的「限制」與「界線」在人類生活中是無法避免的，「形式」或「習俗」也是自然且必要的，儘管如此，這些仍造成人類的分離。而智者，則能夠在與他人相處時，超越上述這些。

The Sufi
< Seeker of Truth >
What is a Sufi? Strictly speaking, every seeker after the ultimate truth is really a Sufi, whether he calls himself that or not. But as he seeks truth according to his own particular point of view, he often finds it difficult to believe that others, from their different points of view, are yet seeking the same truth, and always with success, though to a varying degree. That is in fact the point of view of the Sufi and it differs from others only in its constant endeavor to comprehend all others as within itself. It seeks to realize that every person following his own particular line in life, nevertheless fits into the scheme of the whole and finally attains not only his own goal, but the one final goal of all.
Hence every person can be called a Sufi either as long as he is seeking to understand life, or as soon as he is willing to believe that every other human being will also find and touch the same ideal. When a person opposes or hinders the expression of a great ideal, and is unwilling to believe that he will meet his fellow-men as soon as he has penetrated deeply enough into very soul, he is preventing himself from realizing the unlimited. All beliefs are simply degrees of clearness of vision. All are part of one ocean of truth. The more this is realized, the easier it is to see the true relationship between all beliefs, and the wider does the vision of the one great ocean become.
Limitations and boundaries are inevitable in human life; forms and conventions are natural and necessary; but they none the less separate humanity. It is the wise who can meet one another beyond these boundaries.
