We have simultaneously measured both the explicit movement of palms and the implicit movement of the whole body in the hand contact improvisation. And, we also have compared and analyzed the difference of the measurements between the time when the sympathetic embodied awareness is being generated and when it is not. We have obtained the following results from the comparison and the analysis under the condition that the self-other inseparable relationship is being created through the sympathetic embodied awareness between two persons. First, the implicit movement comes before that of the explicit. Second, the time when those movements occur corresponds between the two persons. Furthermore, chaos attractor is generated within the movements of hands, and there exists a rhythm of a cycle variation for a few to ten seconds. These results suggest that the space-time structure of the inner self changes through the bodily expression. It is expected that this will be an important clue to clarify the dynamics of "Ba" in the co-creative expression.
