There is no religion in the world where there is a possibility of spiritual development outside of the context of that religion. This is only a modern invention. For example, Christian mystics were also Christians. They also went to Church and followed Christian laws. Hindu mystics were practicing Hindus; they didn't kill cows and have steak. They follow the Hindu laws and so on and so forth down the line and Sufism is no exception.

The significance of the vast Islamic scientific tradition for Muslims and especially for young Muslims today is not only that it gives them a sense of pride in their own civilization because of the prestige that science fhas in the present day world. It is furthermore a testament to the way Islam was able to cultivate various sciences extensively without becoming alienated from the Islamic world view and without creating a science whose application would destroy the world of nature and the harmony that must exist between man and the natural environment.

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.

There are millions and millions of Sufis who have existed in Islamic history and have the deepest impact on every aspect of Islamic culture and civilization to philosophy to art to science to social structure to economics who have not met the destiny of al-Hallaj.

How did the Turks become Muslim? They became Muslim through the Sufis. The Arabs never conquered the Turks. There were people in early Islam who were speaking like Hallaj, who spoke about the Truth, about reaching the Truth, about being one with the Truth, and not only they were not killed, but they were great heroes of their own culture, and there is a university in Turkey named after one [Sufi Saint.]

Muhammad was, first of all, a Prophet of course, a beloved and lover of God, a father, an army commander, a judge, a ruler of a community, the King of Medina and later of Arabia, and all of these were combined in him and his destiny, the reason God brought him on earth, was to show how each of the functions which human beings have in life have the perfect form in the prophet.

Only man can stop being fully man. He can ascend above all degres of universal existence and by the same token fall below the level of the basest of creatures.
