Kun (坤 ☷) — The Receptive

Kun (坤) consists of three broken yin lines (☷). The Shuogua commentary associates it with earth, mother, belly, the cow, and cloth — images of yielding, holding, and supporting all things without struggle.

In divination Kun signifies receiving rather than initiating, supporting another's vision, careful preparation, and patience. Doubled, it becomes the second hexagram (重坤) — "Earth over Earth," the perfect complement to Qian.

Recording Kun as softness loses most of what the Shuogua Zhuan actually lists for it: earth, mother, cloth, a cauldron, frugality, evenness, a cow with its calf, a great cart, pattern, the multitude, a handle, and blackness where the earth is concerned. The thread running through them is capacity. These are things that hold, carry or distribute. The Xici Zhuan adds a claim of a different kind, assigning origination to Qian and completion to Kun, which makes Kun a principle of bringing matters to finished form and not merely of yielding.

That is why reading Kun as weakness or absence of will goes wrong so often. The trigram's animal is the cow, yet the hexagram text invokes a mare, and the Tuan commentary explains the choice by saying that the mare belongs to the earth's kind and travels the ground without limit. Compliance here is entirely compatible with covering great distances. A second error maps Qian and Kun onto gender or social rank. The Shuogua offers a family of parents and six children as a way of numbering relationships between trigrams, and what it numbers is sequence, not worth.

Kun's own line statements do not describe a smooth slide into passivity. They open with frost underfoot and the warning that solid ice is coming, pass through a line praising what is straight, square and great, a line counseling that brilliance be kept contained, a tied sack that earns neither blame nor praise, and a yellow lower garment called supremely auspicious, and close with dragons fighting in the open, their blood dark and yellow. The arc teaches reading signals early and knowing where one's portion ends: yin carried to its extreme contends with yang and stops carrying anything at all.

Kun and Qian are the only fully opposed pair among the sixty-four, and they stand first and second in the received order. Two other trigrams are built directly on Kun's body: put a yang line in the top position and you get Gen (艮 gèn), the mountain; put it in the middle and you get Kan (坎 kǎn), water. In the family scheme these are the youngest and middle sons. Structurally, the mountain's stillness and the ravine's danger are both what happens when something hard appears in open ground, one blocking the road and one sunk in the middle of it.

One clause of the hexagram text has been argued over for a very long time: gaining companions in the southwest, losing them in the northeast. One reading follows the Later Heaven diagram, where Kun occupies the southwest and Gen the northeast, so like meets like in one direction and not in the other. Another follows the Tuan commentary, which says that losing companions in the northeast ends in blessing, and treats the loss as the productive move. Both are anchored in transmitted text, and diviners usually decide by whether the question concerns partnership or going alone.

In practice, receiving instead of initiating is only the starting point; what a reading adds is how far you are willing to carry the matter. The hexagram text opens with supreme success and then attaches a condition: going first leads astray, following finds a master. So Kun suits consolidation, accumulation, groundwork and supporting someone else's project, and argues against racing ahead alone. Questions about cooperation and about holding what exists tend to read well, while questions about originating something, or about speed, do not. In the six-line method the Kun house is earth, so timing estimates are generally pushed later.
