This study is an auto-ethnography of the self-reflection experience during the training supervision course in a counseling area of the Korean Transactional Analysis Counseling Association. The biggest issue during this training period was the fear of writing an essay and a doctoral dissertation which were the assignments for training. This study analyzed the cause of fear through self-reflection and described the process of psychological-internal change centered on the theory of transactional analysis. The researcher realized that she had to made composite decision to follow her parent’s orders such as “work hard”, “hurry up”, and “be perfect” as an alternative decision to escape the prohibition order like “do not exist”, which eventually became an internal driver to make her live a tough life. The more she was pressed for the burden of writing a paper and the driver, the more she repeatedly fell into the reduction scenario and spent a depressed time repeating only helplessness and avoidance. However, she got to know during self-reflection that the reason she got an interdict(prohibition order) like “don’t exist” hindered him/her growth as a TA training supervisor, by being connected with the life that she couldn’t expect her mother’s love because of the absence of mother’s caring, and the fear of her father who was too boossy enough to make her feel a sensation of fear, and by being reenacted. The purpose of this study is to describe the process of self-reflection based on TA theory, and the process of deriving the in-depth change of researcher as a self-cultural technology.
