"This case study was started on the premise that a sandplay therapy with its symbolic images in a protected space would be helpful to a child who had serious psychological scars to be able to express his inner anger without resistance and ultimately become whole by following the therapy process which provides safe exploration and positive re‐experiences. The study was centered mostly on the symbols of frog which appeared frequently on the boy’s sand tray, and on the myths of water and flood. The study on the frog symbol began with an ecological model as its base and proceeded to the myths, symbols and the aspect of their transmission. The study on the flood myths began by researching diverse myths of different countries and proceeded to attempt at approaching them with an analytical psychology in mind. The result of the analysis showed that the frog symbol meant that something was becoming conscious from the child’s unconsciousness. It also represented and announced that some kind of transformation was going on or was going to happen. The child was able to muster his inner strength by frequently making trays using water and frog and finally by making Great Flood, he was able to dissolve and reintegrate what was deep in his inner unconsciousness so that he could find his new direction. In conclusion, the child’s experience with symbolic images through the sandplay therapy was effective in helping him to regress safely so he could find stability and integration. It was also effective for him to express properly his negative feelings that are otherwise hard to do in the real world; thus, he could reconstruct his unconscious inner world and become conscious.
