Jung's Psychology
People of all ages from different countries and from varied cultures have read Jung's writings and have experienced moments of "being at home", of feeling seen, of being recognized. This is mainly because Jung has given us the concepts, the techniques and the reasons. His psychology has the lengthy description of, as the title of one of his books states, Modern Man in Search of a Soul. 
His psychology includes the structure of the psyche with its dual reality of consciousness and unconsciousness, personal and collective. It gives us concepts such as the ego, the persona, the shadow, anima/animus, the Self. Jung developed a typology that explains human behaviour as a combination of thinking, valuing, intuition and sensation and that popularized the terms extrovert and introvert. The techniques that characterize depth analysis include dream work with a prospective rather than a regressive outlook; amplification, association, active imagination, etc. In Jungian analysis the relationship between analyst and analysand is primordial. Jung believed that the real cure of soul occurs in that relationship. Without it, no transcendental function or third space container can be constellated so as to allow transformation.
Jungian psychology has opened the doors to the treasure house that is an integrated approach to the human being. It is above all an invitation to self-acceptance and a path to give meaning to your life.
When you realize that you can be the container for the tension and energy created by the struggle of all opposites in your life, then balance, harmony and freedom become possible. Unity becomes a fact, because through symbols one feels the meaning that explains the suffering. The symbols incarnate the archetypes that unite us in our common humanity. The archetypes, the symbols, the images that populate our dreams, our poetry, our myths, our fairy tales, our literature help us perceive the unus mundus. Jungian psychology is the bridge from the individual to the collective and back again. Jung summarizes the feeling of harmony in the following way: "At times I feel as if I am spread out over the landscape and inside things, and am myself living in every tree, in the splashing of the waves, in the clouds and the animals that come and go, in the processions of the seasons."
"To find out what is truly individual in ourselves, profound reflections are needed; and suddenly we realise how uncommonly difficult the discovery of individuality is."
From Jung's Relations Between the Ego and the Unconscious

"The unconscious as we know can never be "done with" once and for all. It is, in fact, one of the most important tasks of psychic hygiene to pay continual attention to the symptomology of unconscious contents and processes, for the good reason that the conscious mind is always in danger of becoming one-sided, of keeping to well-worn paths and getting stuck in blind alleys. The complementary and compensating function of the unconscious ensures that these dangers, which are especially great in neurosis, can in some measure be avoided."
