In the field of medicine, if you're sick you need a doctor. A doctor has already studied how to deal with your ailments, and human beings are imperfect. There any many ailments of the psyche and the soul that need to be treated, and the serious murshid, or spiritual master, is also really a doctor of the soul: a person who can heal the wounds of the soul in the same way as a medical doctor takes care of our physical problems.
Seyyed Hossein NasrThe Shariah has many other functions but also protects the tarqiah; it protects the spiritual path.
Seyyed Hossein NasrSufis 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.
Seyyed Hossein NasrWithout Sufism, Islam would not have spread into two thirds of what we call the Islamic world.
Seyyed Hossein NasrSpiritual guidance needs guidance. It's like comparing walking on the ground and mountain climbing. Once you learn how to walk, you can walk on the ground by yourself, but if you want to climb Mount Everest, you need a guide.
Seyyed Hossein NasrIf 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.
