Return opens with its one strong line at the very bottom of the figure, and the text attached to it concerns distance rather than fault. Legge's translation describes returning from an error that has not extended far, and finds in that no occasion for repentance and great good fortune besides. The error is granted; what the line measures is how far it was carried before the turn was made. A short straying corrected at once leaves nothing behind it, and the whole of this hexagram rests on that observation, that a fault has a size and its size is mostly a matter of time.
The image behind the figure is the winter solstice, thunder buried in the earth, the first light stirring beneath five dark lines. This opening line is that light. It is the only yang stroke present and it stands correctly in an odd place, at the foot of the lower trigram Zhen, movement itself. Nothing has yet grown from it, which is exactly why it is favourable: the returning impulse is small, unopposed, and still entirely within the control of whoever feels it.
Placed at the beginning of the sequence, this line sets the standard the remaining five are measured against. Later lines return admirably, repeatedly, alone, and nobly, and the last fails to return at all. Each is a variation on the distance named here. Great good fortune in this position is not a reward for virtue but the plain consequence of turning back early, while the road home is still short.
