Salam Someone mentioned the name of shaykh Nazim recently, all i have to say is: Tasawuf is meaningless without complete submission to the shariah. if one observes a "shaykh" of tasawuf who does not follow shariah completely (shirk-like practices are encouraged, they shave, shake hands with women, watch women play music etc.) than one should not give bay'ah to that individual but rather run 180 degrees in the opposite direction (paraphrased from Shaykh Hussain Sattar's lectures).
