Also known as: 重艮 · Hexagram 52 · ䷳
Gen Wei Shan is the 52nd hexagram, doubling the Mountain trigram (☶ over ☶). Mountain signifies stopping and rest. The judgement "艮其背，不獲其身" — keeping the back still so that the restless self is not perceived — teaches the art of quieting thought at the right moment.
The Great Image reads "兼山，艮；君子以思不出其位" ("Mountains standing together; the noble person's thoughts do not stray beyond his position"). In divination Gen counsels pause, restraint, and staying grounded rather than forcing progress.
One sentence in the Tuan commentary governs every serious reading of Gen: stop when it is time to stop, move when it is time to move, and when stillness and motion never miss their moment, the way of it is bright. That turns the hexagram from a verdict into a question about timing. The second half of the sentence does most of the work, because it makes moving as much a part of Gen as stopping, and rules out reading the figure as a blanket prohibition.
The classical appendices treat Gen as a hinge in the year's round, not a dead end. The Shuogua Zhuan (說卦傳 Shuō Guà Zhuàn) glosses the trigram as stopping, assigns it the northeast, and describes that corner as where the myriad things complete their ending and complete their beginning, both named in the same breath. It makes Gen the youngest son, obtained at the third seeking, gives it the dog and the hand, and beyond the mountain lists images such as narrow paths, small stones and gateways. The Xugua Zhuan places the hexagram after Zhen with a short remark: things cannot move forever, so they are stopped.
The six line statements form an unusually literal ladder up the body: toes, calves, the waist, the trunk, the jaw, and at the top a stillness called thick or matured. The progression is worth reading as method. Stopping at the toes, before one has set out, draws no blame. Forcing the stop at the waist — the joint that carries the whole frame — is described as a tearing, with danger that sears the heart, the classical picture of stopping too late and too violently. Stopping at the jaw yields speech that has order. Only the top line, where stillness has ripened instead of being imposed, is called plainly auspicious.
The judgement's opening clause has long divided readers, and the two options put the hexagram in different registers. One reading takes the character for back in its plain anatomical sense: still the back, the part one cannot see, and the agitated self goes unnoticed. Another reads it as turning away or facing apart, which lets the next clause, walking in the courtyard without seeing the person, describe two parties turned away from each other. The following phrase about not perceiving the body is read as the physical body by some and as the self by others, shifting the hexagram between a meditative and a social register. Both are ancient, and each yields a coherent hexagram. What neither supports is the flattening of Gen into “nothing will happen”. The northeast attribution makes it a threshold, and the Great Image's counsel that thoughts do not stray beyond one's position concerns not overreaching a role; it is no recommendation to stop thinking or to give up an ambition.
In the stem-and-branch line method the eight doubled hexagrams place the governing line at the top and its counterpart at the third, so the questioner's own position sits at the highest and most static point of the figure while the matter enquired about lodges in the middle of the body-ladder. Readers of Gen usually begin by separating two kinds of stopping: an obstruction arriving from outside, and a halt the questioner is producing themselves. Because both trigrams are identical, Gen more often indicates the second. Matters are described as held in place instead of destroyed, which is to say delayed, blocked, or waiting on a condition that has not yet changed.
Not as a blanket rule. The Tuan commentary pairs stopping with moving and praises stillness and motion that never miss their moment, so the hexagram poses a question about timing and not a prohibition. In practice it usually means the present stretch is not the one for pushing forward: hold position, let a condition ripen, and locate the danger in forcing progress now instead of in waiting.
It is the opening clause of Hexagram 52's judgement. The back is traditionally read as the part of oneself outside one's own line of sight, so stilling it means quieting the self at the point where desire has nothing to look at; the following clause then says the agitated self goes unnoticed. The mechanism is removal, not suppression, which is why the tradition treats the line as a technique and not merely as an ideal. A second old reading takes the same character as turning away, making the clause describe two parties facing apart.
They are the same figure seen from opposite ends. Turning Zhen, Thunder Doubled, upside down produces Gen, Mountain Doubled, which is why they sit adjacent as hexagrams 51 and 52. The Za Gua Zhuan pairs them in four characters: Zhen is arousing, Gen is stopping. In family imagery Zhen is the eldest son and Gen the youngest son, and in the five phases Zhen is wood in the east while Gen is earth in the northeast. Readers often consult them together because movement and its limit are traditionally one topic.
Traditionally it is read as held rather than finished. The line statements are the clearest guide: stopping early draws no blame, forcing the stop late is dangerous, and the top line, where stillness has matured on its own, is the auspicious one. That grades the situation by how the halt came about, not by whether the matter can still move. The usual counsel is to wait in place and keep one's position instead of abandoning it.
The Shuogua Zhuan assigns the trigram that corner and explains it as the place where the myriad things complete an ending and complete a beginning, which is the seam between winter and spring; in the branch system that falls roughly across the chou and yin period. The position is doing conceptual work rather than bookkeeping, since it is what keeps Gen from being a terminus. Its five-phase attribute is earth and its family role is the youngest son. Practitioners read northeast as the responsive direction and the winter-spring seam as the window, though how tightly that seam is mapped onto calendar dates varies between schools.
