The purpose of this study was to describe and examine the phenomenological substance of the art therapy experiences of Zen meditation trainees. The question for this research started with “What experiences do Zen meditation trainees acquire through art therapy?”. Giorgi s phenomenological research method was employed to classify the statements by meaning unit in order to structuralize their experiences. The participants were eight selected Zen meditation trainees who received art therapy and were in their 40s and 50s. The art therapy program was conducted once a week from January, 2016 to March, 2016 with nine sessions and data were gathered from March to October, 2016, by having in-depth interviews. According to the four scientific stages of Giorgi s phenomenological method, 409 meaning units were selected, and 20 sub-constituents, eight core constituents, four superordinate categories were selected. The major findings were as follows: First, the participants continued to undergo inner training through Zen meditation, but they felt there was some room for improvement. Second, they experienced the unique value of art therapy and the art activity as a tool for self-exploration. Third, they made progress in training while they checked their own training and inner world through art therapy as a daily routine task. Fourth, they became accstomed to the training as part of life when they incorporated art therapy into Zen meditation.
