In Taoist thought, Tao is the entire universe, infinite and eternal—what is seen, unseen, and forever beyond human comprehension. The tradition holds that all beings and phenomena are interrelated, and are essentially one. Tao includes both the visible processes of nature and the unnamable, underlying sources of change.
Superior virtue (de) is acquired when one lives in accordance with the essential natural order. Chinese philosophy considers the correct way of life and death to be natural—in harmony with Tao. This is believed to be a life of simplicity, naturalism, unselfishness, quiet solitude, and freedom.
