Assagioli's "Star" diagram shows the relationship our Self has to our personality and our psychological functions. Psychological functions are the basic capabilities we rely on for awareness and for taking action – both internally and in the world. Assagioli's diagram, with its wide variety of functions (intuition, imagination, sensation, etc.), makes it clear how complex – and unique – people are: each of us relies differently on the various functions, emphasizing some more strongly than others.

This map also points to the variety of ways we have of creating change. We can use any psychological function and begin a process that changes us as a whole person. The various techniques in psychosynthesis draw on the various functions. Assagioli's "psychological laws pertaining to will training" explain the processes we use to create change. For instance, when he states that "images or mental pictures and ideas tend to produce corresponding physical conditions and external acts" he shows the creative power of imagery and the mind.

This map is a gift in that it gives a hint of the wholeness and richness of the human being – and of the certainty that growth is possible.
