The second line describes not an image drawn from nature but a quality stated directly. Legge renders it as being straight, square, and great, and adds that its operation, without repeated effort, will be in every respect advantageous. Where the first line warned of what an unwatched beginning could become, the second line shows the receptive way already working exactly as it should: straightforward without deception, well ordered without strain, and ample without excess.
The line occupies the central place of the lower trigram Kun, a position Chinese commentary consistently treats as the seat of a virtue exercised in its purest and most balanced form. Straightness, squareness, and greatness read together as a single description of yielding power perfected: it does not need to force its results, because acting in accordance with its own nature is already sufficient. The phrase without repeated efforts is often read as praise rather than limitation, since only a capacity working correctly from the start avoids having to labor at correcting itself.
Commentary tradition frequently pairs this line with The Creative's own second line, the dragon appearing in the field who benefits from meeting a great man, but notes the difference in register: where the yang line there still seeks partnership and recognition, the yin line here needs neither, since its excellence is self-sufficient by nature rather than dependent on being met or matched. It is the clearest statement in the hexagram of what receptive virtue looks like when nothing obstructs it.
