Thunder rising into heaven itself: Dà Zhuàng is the power of the great — vigor at its peak, strength that can finally act. Its entire counsel concerns what justifies that strength.
Power aligned with what is right advances the world; power alone becomes the goat that butts the hedge and tangles its horns. The wise, this hexagram says, do not even step where order does not sanction. True greatness is strength that has internalized its own limits.
問Dà Zhuàng brings vigor into the heart's affairs — confidence to declare, energy to commit. Its warning is proportion: forcefulness that overrides the other's pace entangles like the butting goat. Strength in love shows as reliability and clear intention, not pressure. Pair the power with patience and it carries everything.
Professionally, this is peak-leverage season: resources, momentum, and position aligned for the decisive move. Its rules: act only where right and power coincide; avoid the first line's premature march from the toes; and prefer the fourth line's quiet axle-strength that carries loads to the display that merely impresses. Test the hedge before committing the horns.
Inwardly, Dà Zhuàng examines your relationship with your own force — will, talent, temper at full strength. The practice is self-sanctioned limits: not treading paths that violate your own order, dropping the stubborn butting with ease when it is recognized. Strength that can stop itself is the only strength this book calls great.
A line speaks only when it is a changing line in your own casting.
