Hexagram-53 in the Sequence of Hexagrams: Gèn (hexagram-52) means stopping. Things cannot remain stopped forever; hence it is received by Jiàn (hexagram-53). Jiàn means advancing.
Stopping must be followed by advancing; this is the principle of bending and extending, waxing and waning. What is born of stopping is advancing, and what reverses stopping is also advancing; this is why Jiàn succeeds Gèn.
Advancing in proper sequence is called gradual; today people regard slow advance as gradual, but advancing in sequence without skipping steps is precisely why it is gradual.
As a hexagram, with Xùn above and Gèn below, it is a tree on a mountain: the height of the tree depends on the mountain, so its height has a basis. Its height having a basis means its advance follows proper sequence; this is why it is Jiàn.
It speaks both of the hexagram's capacity and the meaning of gradual advance. The transformations of Qián and Kūn become Xùn and Gèn; Xùn and Gèn doubled make Jiàn.
Within the body of Jiàn, the two central lines interact; from this interaction of the two lines, male and female each attain their correct positions.
Although the initial and top lines lack Correct Position, yang is above and yin is below, attaining the correctness of honor and humility; male and female each obtain their correctness, which also counts as attaining position.
It stands in direct contrast to Guī Mèi (hexagram-54). When a maiden's marriage can be as correct as this, it brings good fortune. Among all affairs under heaven, none requires gradual advance more than a maiden marrying.
A minister entering the court or a person undertaking an affair certainly ought to follow proper sequence; if one does not follow sequence, overstepping bounds and violating righteousness, misfortune and blame will follow.
Yet weighed by righteousness, integrity, and shame, a woman following a husband is the greatest of all; hence it takes the maiden marrying as its significance. Moreover, male and female are the beginning of all affairs.
Many hexagrams speak of 'favorable to be steadfast,' yet their applications differ: some warn against suspicion of impropriety; some require that the affair must be steadfast to be fitting; and some state that the advantage lies in its inherent steadfastness.
What is meant by warning against suspicion of impropriety is exemplified by Nine in the Second Place of Sǔn (hexagram-41): dwelling in a yin position and resting in joyousness, it is admonished to remain steadfast.
What is meant by an affair having to be steadfast to be fitting is exemplified by Dà Xù (hexagram-26): stating that what is nurtured benefits from being steadfast.
What is meant by stating that advantage lies in its inherent steadfastness is exemplified by Jiàn: stating that the reason the maiden's marriage is auspicious is that it benefits from such steadfast correctness.
This is because it possesses it inherently, not as a cautionary warning. The meaning of Jiàn ought to encompass prevailance, yet it does not mention 'prevailing' because prevailance implies swift penetration, which is not the meaning of gradual advance.
