益 · Yì — Compounding Augmentation
King Wen Sequence #42 (益 Yì — Compounding Augmentation) embodies wind and thunder augmenting each other across the plain. Assigned to the Xun Wind Palace (巽宫八卦 · Subtle Penetration) · 三世卦 (World Line 3 / Response Line 6) and resonant with Late Spring & Early Summer Wind (立夏巽风 · 清明—小满), its six-line binary vector (100011) pairs 震 Zhen (Awakening Initiative) at the root with 巽 Xun (Gentle Penetration) at the crown.
《大象》：風雷，益；君子以見善則遷，有過則改。 ｜ 《彖传》：益，損上益下，民說无疆，自上下下，其道大光。利有攸往，中正有慶。利涉大川，木道乃行。益動而巽，日進无疆。天施地生，其益无方。凡益之道，與時偕行。
Visual Archetype: sails filled by a steady tailwind. When Wind / Wood (Wood) interacts with Thunder (Wood), the primary strategic mandate centers on reinvesting windfall profits into community and R&D. Its Polarity Opposite (Cuo Gua · 错卦) is #32 恒 (Persevering Constancy), its Overturned Inverse (Zong Gua · 综卦) is #41 损 (Disciplined Simplification), and its Nuclear Core (Hu Gua · 互卦) reveals #23 剥 (Stripping Away the Old).
巽宫 · 世爻第3爻 / 应爻第6爻
For decision-makers consulting 益 (Yì) regarding reinvesting windfall profits into community and R&D, the hexagram highlights the interplay between Wood foundation and Wood manifestation under the Wood Palace. Rather than generic haste, align execution with Late Spring & Early Summer Wind (立夏巽风 · 清明—小满) rhythms and inspect whether your natal BaZi chart favors Wood, Wood, or Wood as its Favorable Element (喜用神).
