In *The Robe and the Sword: How Buddhist Extremism is Shaping Modern Asia*, journalist Sonia Faleiro examines the troubling intersection of Theravada Buddhism and nationalism across Sri Lanka, Myanmar, and Thailand. The book introduces readers to extremist figures like Galagoda Aththe Gnanasara, whose inflammatory rhetoric has incited violence against Muslims in Sri Lanka, and Ashin Wirathu, whose 969 movement in Myanmar promotes anti-Muslim sentiment. Faleiro argues that the political patronage enjoyed by these monks undermines the spiritual essence of Buddhism, as reverence becomes linked to worldly power rather than genuine faith. She critiques the absence of a central authority to enforce the monastic code of conduct, allowing transgressions to go unchecked. The book also discusses how the current Thai king, Maha Vajiralongkorn, exerts control over the Buddhist governing body, further intertwining religion with state power. Despite its accessible format, the book aims to expose the dangers of religious extremism while highlighting figures like Abbot Zero and Sulak Rivaraksa, who represent the true guardians of Buddhist values. Faleiro's work serves as a call to protect Buddhism from the polarising forces that threaten its integrity.
