Chapter 2 of 34
黄金策
The workings of the Way of Heaven are profound and unfathomable 🌌; how can droughts or floods be rashly predicted? The lines and images of the Yi hexagrams are subtle and profound 🔮, inherently capable of verifying changes between overcast and clear skies. Forecasting weather should focus on analyzing the Parent Line (symbolizing rain) and the Wife/Wealth Line (symbolizing clear weather), not merely relying on the Five Phases of Water and Fire. If the Wife/Wealth Line is activated 🔥, it predicts clear skies across all directions; if the Parent Line is vigorous 🌧️, then gentle rain will fall throughout the land. The Response Line symbolizes the sky; when encountering emptiness, the certainty of rain or shine is difficult to ascertain. The Self Line represents the earth; if restrained, it indicates sudden and abnormal changes in weather. The Day Master governs the cloudiness or sunshine of a single day 🌤️, while the Offspring Line governs the nine-day changes of the moon's phases 🌙. The shifting of winds and clouds is observed through the Brother Line 🌬️, and thunder and lightning are watched via the Officer/Ghost Line ⚡.
One must combine the progression of the four seasons 🍂🌞🍁❄️ and the mutual generation and restraint of the Five Phases (Metal, Wood, Water, Fire, Earth 🔥🌊🌳⚙️⛰️) for comprehensive judgment. Clear skies encountering the Officer/Ghost Line easily lead to mist and haze; rainy days encountering the Offspring Line may bring rainbows or lightning. When the Response Line aligns with the Offspring Line, the azure sky is flawless; when the Self Line encounters an Earthly Ghost Line (Earth Officer/Ghost), then yellow dust will pervade a thousand villages. Forming a Triple Harmony combination of Wealth but praying for rain shows contradictory hexagram imagery; the Five Phases showing many Parent Lines but praying for clear skies, yet encountering emptiness, is inauspicious. Wife/Wealth transforming into Officer/Ghost indicates unsettled weather; Parents transforming into Brothers signifies unpredictable wind and rain. Parents transforming into Offspring: a long rainbow hangs in the sky after rain 🌈; Brothers transforming into Virtue/Offspring: the sun and moon alternately appear and hide within clouds ☀️. The Parent Line holding the Monthly Ascendant inevitably brings continuous overcast rain; the Brother Line sitting in the Long Life position suggests unceasing fierce winds. If the Parent and Wife/Wealth Lines lack support, patterns of drought and flood can be discerned; if the Virtue/Offspring Line carries punishment or harm, solar and lunar eclipses will surely appear 🌒.
Rainfall is inhibited if the Wife/Wealth Line clashes; clear skies are favorable if the Parent Line enters the Tomb. Offspring hidden, Wife/Wealth flying: even while sun-drying under the eaves, one feels oppression; Parents weak, Officer/Ghost strong: travelers hesitate at the gate, finding it difficult to enter. Virtue/Offspring combines with the Response Line and Wood moves: gossamer threads fill the fields like mist; Officer/Ghost clashes with the body position and Metal is vigorous: gloomy fog fills the sky, obscuring the sun. The hexagram encounters hidden clashes; even an empty line may have a turning point. A line being held in combination: even if active, its effect is difficult to manifest. The Parent Line in combination encounters Ghost clash: thunder sounds, then rain arrives; the Wife/Wealth Line in combination suffers Brother restraint: no wind, no clearing. The Kan (Water) and Xun (Wind) hexagrams interacting ❄️🌬️: snowflakes dance that very day; Yin and Yang lines balanced in strength: sweet rain consoles the farmers today 🌾. The Brother Line, Wood vigorous, aiding Xun Wind: the Wind God rages and howls; the Wife/Wealth Line activated, belonging to Qian (Heaven) Yang: the Drought Demon runs rampant, unleashing its fury.
The momentum of the Six Dragons driving across the sky is due to the Tengshe (Flying Serpent) approaching the Zhen (Thunder) hexagram ⚡; the image of Five Thunders driving lightning arises because the Officer/Ghost issues from the Li (Fire) Palace 🔥. The Earth Star assisting the Parent Line creates skies where clouds move and rain falls; the virtue of Wood supporting the Self/Body Line presents scenes of warm sun and gentle winds. Half clear, half rainy: Wealth and Parent lines both flourish in the hexagram; much fog, much haze: Wealth and Officer lines are both active on the lines. The Self holds the Tongren (Fellowship) hexagram: though clear, sunlight is hazy; the Self approaches the Virtue/Offspring Line: even with rain, thunderclaps are faint. Parent line empty, Wife/Wealth line hidden: one must examine auxiliary line images; selecting dates and periods for corresponding effects requires understanding divination rules. To know the details, one must distinguish Yin and Yang to deduce clear or rainy weather; to understand the subtleties, one must observe weakness and vigor to determine severity. If one can thoroughly investigate the subtleties of the Yi's Way, it will naturally align with the mechanisms of nature 🌍.
The core of this chapter lies in using the changes of line positions (Parent, Wife/Wealth, Offspring, Brother, Officer/Ghost) within the six-line hexagrams of the Book of Changes, along with the mutual generation and restraint of the Five Phases (Metal, Wood, Water, Fire, Earth) and seasonal correlations, to predict weather conditions like overcast, clear, rain, and drought. It emphasizes the idea of "correspondence between heaven and humanity," believing that the subtlety of hexagram lines can reflect natural laws, requiring comprehensive analysis rather than reliance on a single indicator.
In a modern context, this is essentially the ancients' empirical summary based on long-term observation 🌱, similar to early meteorological models. Changes in line images can be understood as symbolic expressions of environmental variables (e.g., humidity, air pressure, wind direction):
In modern application, this can serve as a reference for auxiliary decision-making but should be combined with scientific meteorological data 🔬 to avoid superstition. For example: referencing rainy season patterns in agricultural planning, or consulting multiple weather forecasts before travel.
This chapter reflects the ancients' reverence for and spirit of exploration towards natural laws:
