Six in the second place answers a querent attached to the nearer and lesser of two options. Common shapes are a comfortable friendship that crowds out a demanding mentor, a small project that consumes the time a serious one needed, or an ally who is agreeable rather than useful. The line does not call this wicked. It says that the choice has already cost the other thing, and it invites the querent to look at what has quietly been let go.
Nothing in a reading of this line should suggest that both can be held. The text is exclusive by design, and its usefulness in divination comes from forcing the trade into the open. A querent will often insist that the two attachments are compatible and that the neglected one can be resumed later. The line's structure, with the lesser figure immediately adjacent and the greater one out of reach, is the answer: proximity has already decided the matter unless something is deliberately changed.
Because no misfortune is pronounced, this is a reading that describes rather than warns, and the honest counsel is proportionate. If the querent finds, on looking, that what was released matters more than what was kept, the third line of the same hexagram shows the reversal and treats it as still available. If it does not matter more, the line has cost them nothing but the clarity of knowing which of the two they actually chose.
