The fifth line brings the ruler into the figure and finds him at home. Legge's translation describes the influence of the king reaching his family, says there need be no anxiety, and gives good fortune. The word carrying the line is the reaching. A king is the one person in the classic whose authority is never in question anywhere else, and this line is interested in the single place where authority of that kind does not apply automatically.
The stroke is strong, central and correctly placed at the ruling seat of the upper trigram Xun, and it answers the second line, yielding and central in the lower trigram. The classic builds the whole hexagram on that pair. Two central lines, each correctly placed, one holding the inner position and one the outer, are the structure the figure calls a family, and the fifth line's good fortune is less a personal quality than a confirmation that the pairing is holding.
The absence of anxiety is the specific gift of this station. Households are held together by rule at the first line, by severity at the third and by wealth at the fourth, and every one of those has to be attended to or it stops working. What arrives here does not. An arrangement in which the person at the head reaches the people under them without effort has stopped needing to be managed, and the classic marks that by removing the one burden it usually leaves a ruler carrying.
