In the same way that we have a body and a soul and a spirit, our soul can't walk in the street without our body - we would be dead then. Religion is the same way; it has to have a body, it has to have a form, it has to have structure. Without that, the soul cannot be prepared to follow the tariqah.
Seyyed Hossein NasrLook at Senegal, about 90% of the Muslims in Senegal are Tijani or Qadiri Sufis. Among them, they have very great teachers who have written poems about al-Hallaj, and they have not been killed. In fact, it's Sufism that brought Islam through all of Senegal, right under our noses the last couple of centuries. And you can go down the same line through Indonesia and Malaysia.
Seyyed Hossein NasrWhy does one need a doctor if God has given us our body and we pray to Him for our help?
Seyyed Hossein NasrThere 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.
