Six at the Top is the end of a maiden's marriage, and lacking a correlate, it represents a woman's marriage without completion. A wife is one who continues the ancestral line and offers sacrifices; if she cannot offer sacrifices, she cannot be a wife.
The contents of baskets and hampers are what a wife's duty provides.
In antiquity, the pickle, minced meat, and offerings in the inner chamber were the duty of the queen and consorts; when feudal lords sacrificed, they personally slaughtered the sacrificial animal, as did ministers and grand officers.
Cutting and taking the blood for sacrifice—as ritual says, the blood sacrifice honors the vital spirit.
When a woman undertakes the duties of the baskets and hampers but there is no fruit, with no fruit there is nothing to offer in sacrifice, meaning she cannot conduct the sacrifices.
Husband and wife jointly sustain the ancestral temple; if the wife cannot conduct the sacrifices, the husband cannot sustain the sacrifices. Therefore, slaughtering the sheep without blood also leaves nothing for the sacrifice, meaning they cannot sustain the sacrifices.
If a wife cannot perform the sacrifices, she must be divorced and cast out; this is a marital union without completion. Where could it go that would be advantageous?
