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.

One of the greatest problems of humanity is how to live in a multi religious society without losing one's religion - without relativising everything.

Al-Hallaj has a special destiny. He came at a time when worldliness, the luxury, were inundating the Islamic world. His function was to act as kind of an antithesis to this, and he paid for it with his life, and he was very happy to do so. He smiled as he went to the executioner. That was done because it shook the conscience of the Islamic peoples of that time. But the vast majority, the vast, vast, vast majority of Sufis, they have not met the destiny of al-Hallaj. They have spoken about reaching "the Truth" and there is nothing dangerous about it.

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.

To be modern is to destroy nature.

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.

The Quran mentions the story of Moses and Khidr [a prophet mentioned in the Quran who guided Moses on a revelatory journey], a famous story, in which Moses represents sort of the external understanding of the religion and Khidr represents the inner spiritual understanding of the religion. Moses went on a journey with Khidr and Khidr said, "I will not accept you unless you stop questioning things," which from an external point of view seems strange, but inwardly is very meaningful. This is exactly the question of spiritual guidance.
