Central notion of the traditional interpretation of the I Ching. Meaning: A man living in harmony with the Dao, acting out of a state of inner calm, spontaneously and in accordance with the overall situation. Within the hexagram the great man often refers to the fifth line (if this is a Yang line). It indicates an action from center outward. Ideally, it corresponds with its counterpart, the second line (= the middle line in the lower trigram), which is often regarded as will.
