34 Ta Chuang: The power of the great
Persistence in a righteous course brings reward
The thunder runs over the sky
We can find several times the advice not to exit from a righteous course. Persistence means to proceed as usual, without sudden or big changes.
This sign is coupled with March-April months, in which the sun rise up more abruptly and the weather changes more rapidly.
We could be tempted to read this hexagram as a great power that rise and rule the world, a strong voice that overcome all the others and subdue the opponent. This could also mean that the stronger it is the better the result.
We must read it, on the contrary, as a sign of prudence, balance, wise use of the rising power, because it is growing and fighting with the old power (in this case the cold, obscure, winter, “Yin” power).
The thunder over the sky is a power that may come out of control, like the weather in march-april may very easily be too cold or too hot ot too rainy, this is a period that tell how the whole year will be.
If the rising power is balanced, it will develop even better and everything will flourish richly.
It is clear that this hexagram speak of a changing period, and the risk is a loss of balance between today and tomorrow.
We can notice that in all the I Ching when we find a strong power, we are always dealing with changing situations,
while the quiet periods are empty of power.
So we can also see that I Ching consider always connected the power with the changes, because the power, even if very strong, in the end will always and inevitably produce movements.
