"The Jawidan-nama-yi kabir ('Great Book of Eternity') was the magnum opus of Fadl Allah Astarabadi (d. 796/1394) and provided the basis of the Hurufi movement. Today it is one of the most important known texts belonging to the mystical and messianic current that became particularly active in Iran and Anatolia following the Mongol rule. It illuminates the contemporary reconfiguration of religious and political authority along messianic and charismatic lines that took place in the Islamic East, which arguably contributed to the rise and consolidation of the Ottoman, Safawid and Mughal dynasties. Words of Power is the first comprehensive study of Fadl Allah's seminal work. Orkhan Mir-Kasimov summarises Fadl Allah's biography, charts the history of the Hurufi movement, contextualises the Jawidan-nama within Islamic intellectual history, and considers its lasting impact in the Muslim world."--Bloomsbury publishing.
