In nature, such as strata, water strata, and annual rings, we can find layers that are naturally formed by the passage of time. We also live by building up a lot of things (e.g., memories, emotions, momentary feelings, impressions, etc.). But at some point, we forget them and they were buried. Over time, new things naturally pile up on top of it. However, after new memories or emotions cover it up, the things underneath it cannot even be seen by me at some point. People forget them and only recognize what is visible, at the top. (Of course this is inevitable) But we have to be determined to recognize and look into the many different things in it. If you carefully carve to uncover hidden things, you will soon find out what was underneath and what color it has. It is important to take it slow without forgetting that it has to be discovered. The will and action to look inside again is important. Through such sculptures, I can properly recognize the inside of me and the inside of another being. Once you've gone through the careful and close process of knowing clearly, you can not forget the color inside for a long time. And you can see that it remains a small but meaningful world. The sculpted and completed figures will all be different and contain a universe.
