The components of understanding are Affinity, Reality and Communication.
Affinity is the degree of liking or affection.
Reality is agreement, or that which appears to be, and communication is the interchange of ideas or objects. Together these form an interrelated triangle. Another tool of considerable importance in Scientology, and one that greatly assists interpersonal relationships, is the principle of affinity , reality and communication. These three interdependent factors may be expressed in a triangle. The first corner of the triangle is affinity , which is the degree of liking or affection or lack of it.
