When one talks about being like a dead corpse in the hands of a spiritual teacher it means being able to surrender one's will, specially one's nafs al ammarah, that is a part of our soul which is again a Quranic term, which commands us to evil - we must surrender that. That's what it means. It doesn't make you become part of a cog of a machine.
Seyyed Hossein NasrHow 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.]
Seyyed Hossein NasrFrom it genesis twelve hundred years ago to today, Islamic philosophy (al-hikmah; al-falsafah) has been one of the major intellectual traditions within the Islamic world, and it has influenced and been influenced by many other intellectual perspectives, including Scholastic theology (kalam) and doctrinal Sufism (al-ma'rifah or al-tasawwuf al-'ilmi) and theoretical gnosis ('irfan-i nazari).
Seyyed Hossein NasrIf you want to make a decision in life on what to do, but if you're trying systematically, through spiritual practice, through meditation, through the invocation of the name of God, to walk closer and closer in this life to Him, you need someone to guide you. And God has made it possible in Islam for this guidance to exist.
