This study is to investigate how a middle-aged woman experiences the process of individuation through mandala art therapy and what the meaning of that experience is through a narrative inquiry method. The participants of the study are women in their 40s who are suffering from various psychological symptoms such as a sense of worthlessness and depression and avoidance of people. From November 2017 to June 2018, this participant was given a total of 20 art therapy sessions with Kellogg’s ‘The Great Round’ mandala art therapy. In the process, data such as all interview details, artwork photos, and journals were collected. As a result of analysis, the participants’ experiences werederived into seven themes. That is ‘My mother was a very bad mother’, ‘I didn t want to see my face’, ‘I have difficult interpersonal relationships, I long for love from others’, ‘I became a good mother to me’, ‘Give me, face me and heal my inner wounds’, ‘Now, I stand proudly’, and ‘I think I am a pretty decent person’. The meaning of this experience is ‘discovering the lost me’, ‘I am able to love myself’, ‘I feel more comfortable with my interpersonal relationships and I feel more confident’, ‘My parents are forgiven and I feel sorry for them’, and ‘I have the strength to live as the real me’. Results, A middle-aged woman who could not find the reason for her existence, through her art therapy with the mandala, could get a glimpse of her individualization process to love herself as she is, to nurture her own identity, and to live as her true self.
