This hexagram, named "Da Zhuang," signifies great strength and reveals that when things are in a state of great prosperity, one should adhere to righteousness, maintain humility and balance, and avoid arrogance or rash actions due to strength. It symbolizes thunder in the sky, an imposing momentum, and swift, active movement. This is because impulsivity is the greatest of all taboos in dealing with people and matters. This hexagram indicates an overly irrational and impulsive tendency, making mistakes likely. Specifically, it suggests the possibility of bloodshed, being beaten, or injured. Obtaining this hexagram indicates that it is auspicious to think thrice about all matters. This hexagram has four active yang lines at the bottom and two passive yin lines at the top. The yang lines growing represent movement, akin to a person in their prime. Therefore, it is called Da Zhuang. However, thunder is loud and the sky is bright, which can also be extended to represent a just and upright image. Thus, if one is in the military or engages in sports, occupations that are masculine, they can achieve the powerful momentum of four growing yang lines as represented by Da Zhuang.
