Chinese calligraphy serves the purpose of conveying thought and also shows the 'abstract' beauty of the line. rhythm, line, and structure are more perfectly embodied in calligraphy than in painting or sculpture.
Tao or Dou can be roughly translated into English as path, or the way. It is basically indefinable. It has to be experienced. It refers to a power which envelops, surrounds and flows through all things, living and non-living. The Tao regulates natural processes and nourishes balance in the Universe. It embodies the harmony of opposites (i.e. there would be no love without hate, no light without dark, no male without female.)
é“å¯é“, éžå¸¸é“; åå¯å, éžå¸¸å (dao ke dao, fei chang dao; ming ke ming, fei chang ming) - This is an excerpt from the book Dao De Jing written by Laozi around 600 BC with the meaning as "The Way that can be expressed is not the everlasting Way. The Name that can be named is not the eternal Name."
