Yilin Verse
三幸飛來，自我逢時。俱行先至，多得大利。
Three blessings fly hither; fortune comes to meet me in its season. Traveling together, arriving first; gaining great profit abundantly.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder doubled meets lake over heaven: shock decisive as Breakthrough. Three fortunes come flying in, and I meet my moment of opportunity. Traveling together yet arriving first, one gains great profit. The 'three fortunes' (三幸) descending like birds suggests luck arriving in multiples, converging at the perfect time. The one who moves decisively within the group reaches the goal ahead of all others. From The Arousing to Breakthrough, lake above heaven, the verse captures the moment when accumulated tension finally discharges. Breakthrough is the hexagram of decisive action — the lake's water breaking through the dam of heaven. Thunder's energy, channeled into this single moment of resolution, yields abundance. Fortune favors the one who acts when the moment breaks open.
