The traditional concept of sufism has nothing to do with these hindu influenced practices. Let me give you example of shiekh ahmad sirhindi of akbar times, he was against it even though he was naqshbandi sufi....aurangzeb was also naqshbandi sufi and was against these cultural practices which is called sufism by people today. Malang, jogis, high on bhang and doing crazy dances are not sufis.Still you will find crores of Muslims following the sufi traditions and like you they too have justification for their beliefs.
