“Psychosynthesis: Theory and Practice” is a comprehensive presentation of the doctrine, which made a bold attempt not only to combine all the best that was in previous psychological practices of Freud, Jung, Janet and others, but also to give the very concept of “synthesis” a fundamental new meaning. If previously we were talking mainly only about “restoring the state that preceded splitting,” then Assagioli’s psychosynthesis goes further - to the development of a holistic and harmonious personality. The content of the book is sufficient for deep penetration into the little-known practice of self-knowledge and human self-improvement. Only the first part of the book.
