Six lines, then the text.

Ask a question if you want one. Toss three coins, six times, from the bottom line upward. The sum of each toss is the line: 6 and 9 change, 7 and 8 stay. The primary hexagram and the resulting hexagram are computed from those numbers.

The judgment, the image, and the changing-line statements are James Legge, The Yî King (1882), public domain. The short gloss is ours. Any model note is written after the JSON is fixed.
