The Naqshbandiyya [PDF ebook] 
Orthodoxy and Activism in a Worldwide Sufi Tradition

The Naqshbandiyya is one of the most widespread and influential Sufi orders in the Muslim world. Having its origins in the Great Masters tradition of Central Asia almost a millennium ago, it played a significant role in the pre-modern history of the Indian subcontinent and the Ottoman Empire, and is still spreading today. This volume seeks to present a broad picture of the evolution of the ideas and organizational forms of the Naqshbandi order throughout its history. It combines a synthesis of the vast literature on the order with original research, and shall be an important contribution for those interested in Sufism, Islamic history and Muslim-Christian relations.
