“When I was very young, I remember seeing a black dragon dancing in the cloudy sky […]I was not even a year old when I saw the dragon, and my memory was hazy. Now I think that the dragon I saw dancing in the spring sky must have been somewhere among the magnificent branches of an old cherry tree. When I was working alone in my studio late at night in the early days of UNDULATION, the memory of the black dragon I had seen in my childhood, which I had forgotten for decades, suddenly came back to me. I was suddenly revived. As I looked at the many random lines that I had carved on the entire surface of the work, I was seized with a strange sensation, which gradually began to assimilate with the image of the branches of the old cherry tree in my memory, and finally made me realize an absolutely clear concept regarding the meaning and significance of creation in UNDULATION [...] Draw the dragon. Show the dragon. Carve the love of the dragon on it.’”
