A plethora of books has been written about Fethullah Gülen around the world, most of which are biographies or attempts to understand and present the Hizmet movement and its activities.

In contrast to the above, the aim of this book is to study and introduce the reader to the spiritual side of Gülen. Dr. Yuksel Cahirolu, in this thorough study, brings us closer to the ideas, actions, and thought processes of this spiritual person, who has indelibly marked Turkish society as well as Islamic faith in general.

This book extensively discusses Gülen's works, his views on pressing social, Islamic, and global issues, as well as his scientific knowledge. The author presents Gülen to the reader through statements from individuals who lived and collaborated with him in Turkey and abroad, sharing insights about his ethics, character, and way of thinking and acting.

As Gülen's ideas and motivations have often been misinterpreted or spread incorrectly, Dr. Cahirolu seeks to shed light on Gülen's views on Islam and faith, bringing us closer to the Sufi aspects and spiritual influences that have made him one of the most famous and debated figures of the Islamic faith worldwide.
