The book "The Theory of Complexes by K. G. Jung in the Aspect of Solving Therapeutic Problems" offers an in-depth analysis of the interactions between psychological and physical aspects of human life. It examines how these interactions can influence individual physiology and whether it is possible to overcome severe physiological conditions without the use of medications or surgical interventions. The theoretical foundations of Carl Gustav Jung, particularly his theory of complexes, are considered in conjunction with modern psychological approaches to achieve positive outcomes in therapy. The book highlights the significance of emotionally charged complexes, which can lead to not only psychological disorders but also physiological illnesses. It outlines a way in which the assimilation and dissimilation of these complexes can contribute to alleviating pathological conditions. The monograph is aimed at professionals and individuals interested in psychotherapy and the challenges of life and death.
