Yichuan YizhuanLine statement
Nine dwells in the fourth place as Yang; the fourth is the upper trigram, a high place. Firm Yang in a woman is upright virtue, denoting one who is worthy and enlightened. Having no proper correlate, she has not yet found her match.
Passing the proper season without marrying, it says 'delays the time.' A woman dwelling in an honored and high station, endowed with worthy and bright talent, is what people naturally desire to marry; hence her delaying the time is because there is an appointed time.
She holds back of her own accord, not because she cannot be married off; she waits to find an excellent mate before going. Nine dwelling in the fourth place, though not in Correct Position, abides in yielding, which is the woman's way.
Because of having no correlate, it carries the meaning of delaying the time; and the sage deduced the principle that for a worthy woman to delay the time is because she is waiting for the right moment.
