泰 · Tài — Harmony of Heaven & Earth
King Wen Sequence #11 (泰 Tài — Harmony of Heaven & Earth) embodies warm spring breath rising as heaven and earth embrace. Assigned to the Kun Earth Palace (坤宫八卦 · Receptive Treasury) · 三世卦 (World Line 3 / Response Line 6) and resonant with Late Summer & Autumnal Harvest Earth (立秋坤土 · 大暑—白露), its six-line binary vector (111000) pairs 乾 Qian (Creative Sovereignty) at the root with 坤 Kun (Receptive Devotion) at the crown.
《大象》：天地交泰，后以財成天地之道，輔相天地之宜，以左右民。 ｜ 《彖传》：泰，小往大來，吉亨。則是天地交，而萬物通也；上下交，而其志同也。內陽而外陰，內健而外順，內君子而外小人，君子道長，小人道消也。
Visual Archetype: open imperial courtyard at vernal equinox. When Earth (Earth) interacts with Heaven (Metal), the primary strategic mandate centers on cross-functional synergy and golden-age expansion. Its Polarity Opposite (Cuo Gua · 错卦) is #12 否 (Stagnation & Preservation), its Overturned Inverse (Zong Gua · 综卦) is #12 否 (Stagnation & Preservation), and its Nuclear Core (Hu Gua · 互卦) reveals #54 归妹 (Aligning Role & Timing).
坤宫 · 世爻第3爻 / 应爻第6爻
For decision-makers consulting 泰 (Tài) regarding cross-functional synergy and golden-age expansion, the hexagram highlights the interplay between Metal foundation and Earth manifestation under the Earth Palace. Rather than generic haste, align execution with Late Summer & Autumnal Harvest Earth (立秋坤土 · 大暑—白露) rhythms and inspect whether your natal BaZi chart favors Earth, Earth, or Metal as its Favorable Element (喜用神).
