Its sad that people don't properly research Islam and spread views about the so-called, "different interpretations of Islam". A similar attempt has been made by the author. Sufism is a part of Islam, its not different from Sunni Islam. There have been great Sufis among the Sunni muslims, Imam Ghazali, Khwaja Mohiuddin Chisti, Hazrat Nizammudin Aulia e.t.c., for example. Sufism is about meditation , prayer, introspection, a fundamental part of every religion, its not a different interpretation of Islam. Its not that one interpretation of Islam is tolerant and another is not, Islam itself is tolerant, any interpretation that contradicts this fundamental feature is wrong. I would suggest to every thinking Indian, to try and learn about the spirit of Islam honestly instead of listening to canards, lies and suppositions.
