Zensunni

Zensunni in Frank Herbert's Dune series is a religious belief that is a hybridization of principles of Zen Buddhism and Sunni Islam. In the fictional far future of human civilization portrayed in the series, various ethnic and political groups adhere to this worldview, including the Fremen, originally the "Zensunni wanderers."

The accession of Paul Atreides as Emperor and the expansion of Fremen influence throughout the Imperium widely popularized the study of Zensunni beliefs.

Eventually, it is revealed that the Bene Tleilax culture is a religious society based entirely on the Zensunni religion, and in the final works of the Dune series, members of the Bene Gesserit Sisterhood portray themselves as Zensunni believers in an attempt to manipulate Scytale, the last surviving member of the Tlielaxu.
