Opportunity

Energy gathering before release.

The situation

Something is about to move and you can feel it. Whoever is prepared when it breaks captures it.

What it asks of you

Get ready now. Enthusiasm without preparation is just noise.

Where it leads

The six lines

1. initial Enthusiasm that announces itself. 鳴豫，凶
2. second Firm as a stone and not for a whole day either. Knowing before the day is out. 介于石，不終日，貞吉
3. third Looking up at someone else for your enthusiasm brings regret. Hesitating brings it too. 盱豫悔，遲有悔
4. fourth The enthusiasm comes from you and much is gained. Don't doubt it — friends gather like hair to a clasp. 由豫，大有得。勿疑，朋盍簪
5. fifth Persistently ill, and persistently not dying. 貞疾，恆不死
6. top Enthusiasm gone dark and set in its ways. If it can still change, nothing goes wrong. 冥豫成，有渝无咎

The line texts are the oldest layer of the book. They are pictures, not instructions, and they are meant to be held against your own situation rather than decoded.

How this one is built

Written out as six lines, bottom to top, this pattern is 001000 — a solid line is 1, a broken line is 0. Every relationship above is arithmetic on those six digits, not interpretation: reverse the order and you get the other side, flip every digit and you get the opposite reading, take the middle four and you get what sits underneath. Anyone can check the result, which is what separates a structure from a fortune.

The sequence is built the same way. The sixty-four are arranged in thirty-two pairs, and turned upside down it becomes Humility. The rule holds for all thirty-two pairs without exception — twenty-eight joined by reversal, four by inversion.

In the received order it sits between Humility and Following. The order is not alphabetical or random: the old commentary reads it as a chain, one situation giving rise to the next.
