Six in the second place is a reading a querent should resist improving on. Great good fortune is promised, the promise carries no qualification, and the only condition attached is one of position rather than of action: the subject is in his place, in yellow, which the commentary reads as having attained the central course. Nothing is asked for. The line describes a person already standing where they ought to stand.
The counsel that follows is therefore about restraint rather than initiative. In a hexagram whose subject is light with no substance of its own, the fortunate position is the one that has found a proper attachment and holds it without fuss. Somebody drawing this line usually has less need of a new plan than they believe, and the real risk in the reading is that a person shown great good fortune will go looking for something to do with it.
When the line changes, the lower trigram Li becomes Qian and the figure becomes Great Possession, King Wen 14, a single yielding line in the ruling seat with strong lines gathered beneath it. That reads as a consequence rather than a warning. What the second line already has, the centre held modestly while attached to something firm, is the disposition by which a person comes to hold a great deal without having grasped at any of it.
