The translation field is an Oriens clean-room translation from the recorded Chinese judgment text. English titles and commentary are Oriens editorial material, distinct from the received text.
Great power receives only one condition in the judgment: steadfastness is favorable. Force is therefore not self-justifying. Capacity becomes useful when it remains answerable to purpose, limits, and those affected by its use. Before acting from authority, wealth, expertise, or physical strength, ask what standard will restrain you. Power deserves confidence only when correction is possible and consequences are being carried fairly.
The judgment is exceptionally brief: steadfastness is favorable. The title, Great Power, establishes the condition under discussion, but the text does not celebrate domination, conquest, or unrestricted force. By attaching favorability to steadiness, it places power under a criterion rather than treating strength as its own warrant. The brevity itself is instructive: the hexagram refuses to elaborate on what power should accomplish, leaving the reader to hold capacity and restraint in the same breath without resolution.
Thunder over Heaven is the trigram structure, presenting force in an elevated and expansive field. The thunder moves within the heaven's vast reach, suggesting power that operates within a larger order rather than against it. Later Image Commentary draws an ethical lesson about refusing to proceed along what is improper. That formulation belongs to the commentary tradition; it helps clarify that capacity and legitimacy are not identical. The original text does not define what is improper, leaving the ethical work to context and judgment.
In modern settings, power includes office, money, expertise, reputation, physical ability, or control over information. The hexagram asks not whether you have power but how you hold it. Test its use by asking who can question it, who carries the consequences, and what boundary would stop it. Restraint is not timidity when action can affect others deeply. Great power is most credible when it can explain its purpose, disclose its costs, accept review, and correct course without requiring the vulnerable to absorb every mistake. The card does not promise that restraint will be rewarded; it insists that restraint is the condition under which power remains worth having.
