君子終日乾乾，夕惕若，厲無咎。
In the third NINE, undivided, (we see its subject as) the superior man active and vigilant all the day, and in the evening still careful and apprehensive. (The position is) dangerous, but there will be no mistake.

In the received Zhouyi text, line 3 of hexagram 1 is a strong (yang) line occupying the third line, at the threshold between the lower and upper trigrams — in the received text a classic place of unease. The classical line statement — 君子終日乾乾，夕惕若，厲無咎。 — 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 1 Line 3
What does line 3 of hexagram 1 say?
The received text reads: 君子終日乾乾，夕惕若，厲無咎。 In James Legge's 1882 translation: “In the third NINE, undivided, (we see its subject as) the superior man active and vigilant all the day, and in the evening still careful and apprehensive. (The position is) dangerous, but there will be no mistake.”
Which hexagram does line 3 change hexagram 1 into?
Changing only line 3 of hexagram 1 (乾, “Force”) gives hexagram 10 — 履 (lǚ, “Treading”). 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.
