需 · Xū — Strategic Waiting
King Wen Sequence #5 (需 Xū — Strategic Waiting) embodies rain clouds gathering patiently across the western sky. Assigned to the Kun Earth Palace (坤宫八卦 · Receptive Treasury) · 游魂卦 (World Line 4 / Response Line 1) and resonant with Winter Solstice Abysmal Water (冬至坎水 · 大雪—大寒), its six-line binary vector (111010) pairs 乾 Qian (Creative Sovereignty) at the root with 坎 Kan (Abysmal Depth) at the crown.
《大象》：雲上於天，需；君子以飲食宴樂。 ｜ 《彖传》：需，須也；險在前也。剛健而不陷，其義不困窮矣。需有孚，光亨，貞吉。位乎天位，以正中也。利涉大川，往有功也。
Visual Archetype: harbor lighthouse awaiting favorable tide. When Water (Water) interacts with Heaven (Metal), the primary strategic mandate centers on accumulating liquidity before a market inflection. Its Polarity Opposite (Cuo Gua · 错卦) is #35 晋 (Sun Rising Over the Earth), its Overturned Inverse (Zong Gua · 综卦) is #6 讼 (Conflict & Arbitration), and its Nuclear Core (Hu Gua · 互卦) reveals #38 睽 (Harmonizing Polarities).
坤宫 · 世爻第4爻 / 应爻第1爻
For decision-makers consulting 需 (Xū) regarding accumulating liquidity before a market inflection, the hexagram highlights the interplay between Metal foundation and Water manifestation under the Earth Palace. Rather than generic haste, align execution with Winter Solstice Abysmal Water (冬至坎水 · 大雪—大寒) rhythms and inspect whether your natal BaZi chart favors Earth, Water, or Metal as its Favorable Element (喜用神).
