L. Ron Hubbard's seminal – and controversial – work was Dianetics: The Modern Science of Mental Health, written in 1950.
The Church of Scientology International (CSI) serves as the central administrative body that provides oversight for local Scientology churches and organizations. Its primary responsibilities include coordinating the activities of the international movement and promoting the church on a global scale.1
While the CSI manages these organizational and promotional efforts, it is distinct from the Religious Technology Center (RTC), which holds ultimate ecclesiastical authority, owns the movement's trademarks, and ensures the proper application of Scientology's "spiritual technology."1
