a yellow circle, indicating this line as the governing ruler of the hexagram Nine in the fifth place means:

Flying dragon in the heavens.
It furthers one to see the great man.


Here the great man has attained the sphere of the heavenly beings. His influence spreads and becomes visible throughout the whole world. Everyone who sees him may count himself blessed. Confucius says about this line:
Things that accord in tone vibrate together. Things that have affinity in their inmost natures seek one another. Water flows to what is wet, fire turns to what is dry. Clouds (the breath of heaven) follow the dragon, wind (the breath of earth) follows the tiger. Thus the sage arises, and all creatures follow him with their eyes. What is born of heaven feels related to what is above. What is born of earth feels related to what is below. Each follows its kind.
