Sufism has always had the function of purifying Islamic ethics and that fasting and tazkiya is like lighting a lamp.

Tariqah [The Spiritual Path] without the Sharia [Islamic Law] is like having a pistachio tree without the shell. Or a walnut, a walnut cannot grow on a tree without having a shell, and the food that you eat is inside the shell.

Justice is inseparable from truth in human life.

If you have a billion Muslims, 900 million of them were not brought into Islam by any kind of invasion, but most of them through the Sufis, because human beings are such that they are affected by people of spiritual character. Certainly when they display nobility and hospitality and gentility and love and are not selfish or aggressive, and they are honest.

At all costs we should avoid considering our love of God to be superior to the love of the other for GodLet us love God and leave it for Him to decide on the intensity and sincerity of our loves, as well as of our differing views of Him

People who were also traders were also men of Sufism, as we see around Java, people who were outwardly trading but were also men of very high spiritual character. Otherwise no trader would be able to convert a person from one religion to another. It was because they were men of spiritual character.

In Islam, there is no priesthood and each person stands before God, like in the daily prayers, without an intermediary. That's in contrast to Christianity, where during the Eucharist, a priest has to officiate and the priest functions as a link - at least in Catholic Christianity - between the laity and God.
