The eight-pointed cross represents the eight dynamics of life through which each individual is striving to survive....
To be able to live happily with respect to each of these spheres of existence is symbolized by the Scientology cross.
As a matter of interest, the cross as a symbol predates Christianity.
This Scientology symbol is an S imposed over two triangles. The S stands for Scientology. The two triangles represent important concepts in the Scientology
religion. The lower triangle is made up of affinity, reality and communication, which together lead to total understanding. The top triangle consists of another set of closely interrelated factors: knowledge, responsibility, and control.
