Only effortless ease is complete and thorough ease. This is a Daoist concept on physical and mental freedom, which had an impact on ancient artistic creation. According to Zhuangzi (369?-286 BC), people fail to achieve peace because they lack inner strength, not because of external factors. lf the mind is full of distracting thoughts, always drawing a clear-cut line between all things and weighing gains and losses, then the soul will be ill at ease even though external conditions maybe comfortable. Only if all attempts at differentiation are abandoned and all distracting thoughts eliminated, can true ease and tranquility be achieved, and even unpleasant external circumstances be resisted. This thought enlightened the concept of aesthetic freedom in ancient literature and art.
