This term refers to a relaxed and unencumbered approach to people and things. To be unattached, one needs to keep at arm’s length when he comes into contact with other people or things. He should not be too detached, thus unable to have contact with people or objects and know them intimately. Neither should he become too close to people or objects and be influenced by them. He should stay comfortably independent from the people or object under study so as to gain a deeper understanding of them.
Confucius said, “One should follow Dao, adhere to virtues, embrace benevolence, and pursue freely the six arts of rituals, music, archery, charioting, writing, and arithmetic.” (The Analects)
One will need to rely on nothing if he is able to follow the rules of nature, manage the changes of weather, and enjoy everything freely in the infinite universe. (Zhuangzi)
