There is not much to put in this section yet that I am aware of. That is one reason for writing the book! Much of what has been written about Sufism in the West (by academics) is about Westerners adapting Sufism and usually de-islamising it.
Richard Cook’s paper about Mirpuri Sufism is significant because so many of the people of Pakistani heritage in the West are Mirpuris. The paper is also available under South Asian Resources.
If you know of anything relevant to mission to Sufis in the West, please get in touch.
