Gui癸

The oracle glyph of Gui shows crossed arrows, or streams converging from four directions. The Shuowen: "Gui — winter, when water and land lie level and can be measured." From that measuring, Gui shares a root with kui, "to calculate and plan" — a computational gene hidden in the character.

Its element image is Yin Water: rain, dew, frost, the underground spring. Gui ends the ten stems yet feeds straight into Jia's beginning — rain soaks the soil, and next spring the sprout cracks the ground. The cycle closes, and closes at Gui.

Gui's Lu is in Zi, peaking through winter. Yin Water is softness itself: it contests no channel, storms no dam, yet seeps into every crack and feeds every root.

The Di Tian Sui: "Gui Water, weakest of all, yet it reaches the heavenly ford; finding the dragon it moves, and its transformations are divine." The frailest dew rises to become cloud and rain; touching Chen the dragon (the water store) it commands the weather. The weakest stem holds the strongest power of transformation — soft taken to its limit becomes reach. With that philosophy, Gui closes the system of ten.

Wu combines with Gui into Fire — the "loveless combination," mountain wed to rain, a mismatch in scale. In practice: both exposed, each detains the other — the mountain intercepts the rain's nourishment, the rain softens the mountain's mass — and the Officer (or Wealth) axis is rewritten.

Gui clashes with Ding: rain onto lamplight, with Gui holding the pitcher — the exposure Ding dreads most. Yet Gui has its own fears: Ji Earth's mud clouding the spring, Wu Earth's rammed wall stopping the seep.

On the day stem Gui is the Gui Water Day Master — the hidden-spring personality, read fully on that page. Elsewhere by Ten God: to Ding Fire, Seven Killings (rain at the lamp); to Yi Wood, Indirect Resource (the dew every flower waits for); to Wu Earth, Direct Wealth and combination partner — for a Wu Day Master, this Wealth star arrives already entangled.

Gui's classic in-chart office is moistening: summer Wood, scorched Fire-Earth charts — one exposed Gui is the timely rain. Among seasonal-balance gods, Gui and Bing are the two most-summoned characters in the book.

Tenth and last, Gui is the full stop of the stems. Classical medicine named the menstrual tide "Tian Gui" — "heavenly Gui arrives at twice seven years," says the Yellow Emperor's Classic — life's own tide named after the most Yin of waters: the deepest cultural borrowing of the Gui image.

Among cycle years, Gui-Hai stands apart: the sixtieth and final pairing, both stem and branch at their last station, with JiaZi opening a new round the following year. The ancients called it "the year of returning to the root."
