Devotional practices of Sufis
The devotional practices of Sufis vary widely. This is because an acknowledged and authorized master of the Sufi path is in effect a physician of the heart, able to diagnose the seeker's impediments to knowledge and pure intention in serving God, and to prescribe to the seeker a course of treatment appropriate to his or her maladies. The consensus among Sufi scholars is that the seeker cannot self-diagnose, and that it can be extremely harmful to undertake any of these practices alone and without formal authorization.
Qawwali (Music)
Qawwali is a form of Sufi devotional music popular in South Asia, usually performed at dargahs. Sufi saint Amir Khusrau is said to have infused Persian, Arabic Turkish and Indian classical musical styles to create the genre in the 13th century. The songs are classified into hamd, na'at, manqabat, marsiya or ghazal, among others.
