In Islam, we believe that it is God himself who is the ultimate guide - Al Hadi - one of the names of God is Al Hadi, the Guide. But at the same time, God has provided within the Islamic revelation the possibility of spiritual guidance through human beings, because then everyone can have direct access to God.
Seyyed Hossein NasrIn 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 NasrThere 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.
Seyyed Hossein NasrMany people have criticized Islam for being just automatic, having no individuality, just surrendering your will to God, but we Muslims know very well that every moment of the day we have to practice the fact that to surrender one's self to God is an act of free will.
Seyyed Hossein Nasr300 years after the rise of Islam there were Zoroastrians in Iran. The Muslim armies never forced people to accept Islam. It was only within Arabia that God ordered the idolaters to have a choice of either embracing Islam or fight against Muslims, because He wanted to remove this terrible idolatry that exited there. But outside Arabia where Islam met Christians, Jews, Zoroastrians and Hindus, they were given a choice by and large. That's why many Christians and Jewish communities survived in the Muslim world, but gradually many of them embraced Islam for different reasons.
