In the received Zhouyi text, line 4 of hexagram 55 is a strong (yang) line occupying the fourth line, risen into the upper trigram. The classical line statement — 豐其蔀，日中見斗，遇其夷主，吉。 — is what commentators from the Ten Wings onward have read as the figure's own commentary on this one position. James Legge's 1882 rendering, quoted above, keeps the imagery of the original: each line of a hexagram is read as a stage of the same picture, and this page collects the source text for that stage. If you treat the line as moving in the traditional way, flipping it alone produces the changed hexagram linked above; readers have long used that pair of figures to compare a situation as given with the same situation one line different. As always with classical divination texts, this is presented for cultural and reference interest — the text itself carries no prediction about any modern reader's situation.
Questions About Hexagram 55 Line 4
What does line 4 of hexagram 55 say?
The received text reads: 豐其蔀，日中見斗，遇其夷主，吉。 In James Legge's 1882 translation: “T he fourth NINE, undivided, shows its subject in a tent so large and thick that at midday he can see from it the constellation of the Bushel. But he meets with the subject of the (first) line, undivided like himself. There will be good fortune.”
Which hexagram does line 4 change hexagram 55 into?
Changing only line 4 of hexagram 55 (豐, “Abounding”) gives hexagram 36 — 明夷 (míng yí, “Darkening of the Light”). This is the classical way a changed hexagram is derived from moving lines.
Are line pages available for every hexagram?
Yes. Every one of the 64 hexagrams now has six line pages — one per line from the bottom line up to the top line — each with the classical Chinese text, Legge's 1882 translation, and the changed hexagram that line produces when it moves.
