It is clear that free-mixing takes place. He is certainly not Shaykh al-Kamil as he is yet to learn that the Shari'ah al-Muhammadiyyah is above everyone...

Who is Sheikh Postneshin Jelaleddin Loras? Is he a Sunni and a real Shaykh or one of these modernist sullah-kulli types. I ask because my best friend is thinking of joining the Mevlevi Order and wants to know if this person is a genuine Shaykh or dodgy!
