Six at the top means:

One falls into the pit.
Three uninvited guests arrive.
Honor them, and in the end there will be good fortune.


The waiting is over; the danger can no longer be averted. One falls into the pit and must yield to the inevitable. Everything seems to have been in vain. But precisely in this extremity things take an unforeseen turn. Without a move on one's own part, there is outside intervention. At first one cannot be sure of its meaning: is it rescue or is it destruction? A person in this situation must keep his mind alert and not withdraw into himself with a sulky gesture of refusal, but must greet the new turn with respect. Thus he ultimately escapes the danger, and all goes well. Even happy turns of fortune often come in a form that at first seems strange to us.
