The Enneagram is initially a tool for understanding the world from the most ancient traditions. It has today become a method of psychological classification of humans into 9 psychological types, characterized by their limited vision of the world. Far from locking oneself and others into sclerotic and definitive classifications, in this work the author considers that the typology of the Enneagram can become the basis of global work on one's being. This work of knowledge, of acceptance, with this concrete tool, allows you to act in a targeted manner to overcome your limiting beliefs and your relational difficulties in particular. It is therefore a work of hope for each of us.
