The Book of Changesfifty-oneHexagrams, thunder on top (thunder) and thunder on bottom (thunder), heavy thunder stacking and shaking, with a majestic voice.

The hexagram reveals that both the upper and lower hexagrams are for shaking, which is for thunder, for movement, and for the eldest son. Double thunder strikes symbolize the continuous vibration and the momentum of breaking through the old and establishing the new.Thunder roars back and forth, shaking all things in heaven and earth, bringing both intimidation and fear, as well as awakening dormant vitalityFear is the prelude to awakening, turbulence is the pain of rebirth.

When the double thunder rings through the sky, it awakens not only the vitality of the earth's deep sting, but also the ancient courage of humanity to face impermanence and adapt to change.
