What does a lamp do? The lamp is like a horse that is running but stays put. But by virtue of being a lamp it illuminates the space around it. Therefore, the practice of purifying one's soul, of living virtuously, has tremendous impacts upon the ethics of the surrounding society.

Look 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.

Once you've fallen in love, it's turned around your whole life. You keep thinking about this girl all the time instead of thinking about other things. Since the object of love is that particular person, being separated brings about a longing and pain.

Militarily, the great movements of resistance against colonial powers in the 18th and 19th century were almost all from Sufis: Imam Shamil in Caucasia, Amir Abd al Qadir in Algeria, The Barelvi family in the modern province of India, today which is Pakistan, and you can go down the line.

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.

The Shariah has many other functions but also protects the tarqiah; it protects the spiritual path.

Sufism has always had the function of purifying Islamic ethics and that fasting and tazkiya is like lighting a lamp.
