the concept of nine personality types related to each other according to a geometric scheme (on a circle at an equal distance from each other), and the relationship between them. The Enneagram model is not recognized in scientific circles and is not used in psychological research, but is widely used in various teachings and schools in the field of esotericism, introspection, personal growth, and spiritual development. Today, there is no single unified understanding of the Enneagram and no agreement among “spiritual teachers” on all the details of the teaching. Accordingly, there is no generally accepted typing procedure: each author compiles tests based on his own intuitive understanding of the concept, there is no need to talk about any validity.
