The hexagram is conventionally called Difficulty at the Beginning, and the image usually given for it is a plant pushing through hard ground, an obstruction that is a sign of life rather than of failure.
The reading follows from that. It describes a start that is not going smoothly, in a situation where the difficulty is structural rather than a verdict: things are tangled because they are new, not because they are wrong. Wilhelm's judgement advises that it furthers one to appoint helpers, which is unusually concrete practical advice and is one of the passages where the text sounds most like a person talking to another person.
The advance-and-retreat line at the bottom is the one most often quoted, and it carries the hexagram's characteristic instruction: movement that is real but not yet committed. The reading is generally that the querent should establish a position before pressing forward, and that hesitation here is competence rather than weakness.
The counterpart hexagram, Youthful Folly, is this figure turned upside down, and the pair is worth reading together. The King Wen sequence is built substantially out of such pairs, one hexagram followed by its inversion, or where inversion produces the same figure, by its opposite, and noticing the pairing usually says more about a hexagram's place in the book than any individual commentary does.
Translations diverge less here than on the first two hexagrams, largely because the imagery is concrete enough to constrain the translator.
