The problem of the human soul is one of the most topical issues in philosophical research. Johannes Eckhart is a significant representative of mysticism of the Middle Ages. His doctrine originates from scholastic and mystic sources. As a true Christian, he describes the human soul as the Kingdom of God. Thus, it relates to both person and God. In its sacral depth, in its "sparkle", the human soul has an ability to reach the God. This specific knowledge begins with the activity of the will of a person. There is a potentiality to come closer to God using one's freedom. The process of improvement of a person results in a state of detachment. This book will be interesting not only for scientists but also for other people who are seeking to find out their origin and purpose, their place among the others and the potentiality of their souls in revealing something superior in themselves.
