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.

Justice is inseparable from truth in human life.

Sufis have always been those that have tried to purify the ethics of Islam and society. And they don't have their hands cut off from the external action at all. For example, the bazaar in which the Sufis were very strong always dominated economic life in Islamic world. They could give a much more sane and Islamic form of activity when the economic life of Islam moved out of the bazaar to new parts of Islamic cities with modernized Muslims, who took it in another light and it became very, very anti Islamic, and much against many of the most profound practices of Islamic societies.

The environmental crisis has deep spiritual, philosophical, and religious roots and causes. It is not merely the result of bad engineering.

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.

In fact, the machine doesn't have the consciousness we have, the free will that we have, and to surrender one's free will, not in every matter but in spiritual matters, to a spiritual teacher is in a sense a lower level of surrendering one's will to God.

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