The third edition of 『Analytical Psychology』, which has been established as a representative introductory text to Jungian analytical psychology since its first publication in 1978.
In this book, which condenses Jung's thought based on insights gained through direct analytical training and experience, the author introduces Jung's life, the background of the birth of analytical psychology, key concepts and theories, and Jung's specific analytical work in a concise and easy-to-understand manner.
This is a must-read for anyone who wants to learn about analytical psychology.

In this book, the author uses as much of the information as possible from C., the founder of analytical psychology.
G. Jung tried to introduce this psychological theory in his own words.
However, it goes without saying that the author's subjective views, gained through his analytical training and experience in this field to date, will have influenced the presentation of his doctrine.
Therefore, this book has the characteristic of being a theory of analytical psychology that the author understood and assimilated through his own experience. --- p.9

Unlike psychoanalysis, analytical psychology originally had no distinct schools.
This is because Jung's theory did not insist on maintaining its absoluteness as a hypothesis, and also because in the field of psychotherapy, the therapist's basic attitude was considered more important than the treatment method, so differences in methods or supplementation of hypotheses did not create an opportunity to form a school.
Perhaps it could be said that Jung's hypothesis is an archetypal product that expresses the most fundamental human nature and therefore does not need its opposite, but only its expansion and deepening through various amplifications.
Analytical psychology is an empirical psychology and a hypothesis, and its usefulness depends solely on whether the hypothesis is effective or not in the field of psychotherapy. If we follow Jung's position that hypotheses can be modified and supplemented anytime and anywhere, then it is not surprising that people belonging to the Jungian school each have different voices based on their own experiences, and it is characteristic of Jungian thought to encourage and allow such diversity.

What are the characteristics of the unconscious?
It is not composed solely of what is repressed from consciousness, as Freud initially thought.
In the unconscious, there is a layer that is made up of all psychological content that was once conscious and was repressed, or that was simply forgotten without the mechanism of repression in action, or that had such a small impact on consciousness that it was not conscious. On the other hand, there is a layer that is present from birth but has a great influence on mental functioning without being recognized by consciousness.
The former is called the 'personal unconscious' because its content is based on the individual's special experiences after birth and is different for each individual, while the latter is called the collective unconscious (or universal unconscious) because it exists innately and has a universal nature for all humans, transcending time and space.

If you believe that if the unconscious becomes conscious in this way, the unconsciousness will eventually disappear and you will become a completely enlightened person, then you are wrong.
The unconscious is an endless world.
No matter how much you become conscious of it, the unknown world remains.
Therefore, the self always transcends the 'I (ego).'
Since 'I' am contained only within that great circle, the ego cannot know itself.
Therefore, Jung says that self-realization is not necessarily about becoming complete, but rather about becoming relatively whole.

Analytical psychology is a discipline, not a worldview.
Academic knowledge cannot become a worldview.
So, analytical psychology does not give patients a pre-existing worldview.
However, it provides materials or means to build or reform a worldview.
What analytical psychology can contribute to renewing our worldview is the recognition of the unconscious world and its creativity, as well as the realization of the existence of a world of myths that are difficult to grasp even rationally, forming its underlying source.
“Eternity, the most important characteristic of primitive life, is completely absent from our lives.
We are isolated from the eternity of nature by building up a wall of rationalism around us.
Analytical psychology seeks to break down this barrier by rediscovering the fantastic contents of the unconscious that rational reason has condemned.
These prizes are beyond the barriers, they belong to our nature, our very nature.”
