Curiosity is a part of human nature. Being curious to explore nature is the origin of creativity.
People set measurement and standard, seeking for balance to maximize efficiency and tighten controls. These things, however, do not exist in nature，no
leaves are exactly the same, nor the texture of a stone is exactly symmetrical.
The structure of nature is arbitrary, loose and aimless, compared to the high tension of the society we live in today. Fickleness of modern society is result of
people's extremely proposeful and regular life style. Owing to the fickleness we often lose sensitivity to beauty; but owing to the high tension we are
exceedingly in need of spritual healing from the beauty of nature.
