Jin follows in the Sequence of the Gua: Things cannot remain strong forever, hence it is received by Jin. Jin means advancing. Nothing in existence remains strong and stops forever; once flourishing and strong, it must advance. This is why Jin succeeds Great Strength.
As a Gua, Li is above Kun, meaning brightness emerges above the Earth. As the sun emerges from the earth and ascends, it becomes ever brighter; hence it is Jin. Jin carries the meaning of advancing into vast brilliance and greatness.
Generally, when things gradually flourish, it is called advancing; hence the Tuan says: 'Jin means advancing.' Some hexagrams possess the four virtues while others do not, each according to what is appropriate.
Outside of Qian and Kun, those that mention 'supreme success' originally possess it; those that mention 'favorable to persevere' lack it in part and need it to achieve merit. Those that differ include Ge and Jian, as seen in each Gua.
Jin is flourishing and has no need to mention virtues; because Jin's brightness is so abundant, it needs not speak of success. Complying with great brightness, there is no need to caution about correctness.
Jin is a time of advancing into flourishing; great brightness is above, and the lower trigram complies and attaches below—the image of feudal lords serving the king. Therefore it is the Marquis of Kang. The Marquis of Kang is a marquis who governs in peace.
When great brightness is above, one who shares this virtue in compliant attachment is a marquis of peace and order; hence he receives numerous bestowed horses. Chariots and horses are heavy bounties; fán-shù means vast and numerous.
Not only are the gifts generous, but he is also treated with intimate courtesy, being granted audience three times within a single day, expressing the utmost favor of reception.
In the time of advancing into flourishing, the superior is bright and the subordinate is compliant; ruler and minister find mutual accord.
For the one above, it means advancing in brightness and flourishing; for the minister, it means ascending to high prominence and receiving glorious favor. The Tuan says: Jin means advancing.
