Six in the second place means:

Contemplation through the crack of the door.
Furthering for the perseverance of a woman.


Through the crack of the door one has a limited outlook; one looks outward from within. Contemplation is subjectively limited. One tends to relate everything to oneself and cannot put oneself in another's place and understand his motives. This is appropriate for a good housewife. It is not necessary for her to be conversant with the affairs of the world. But for a man who must take active part in public life, such a narrow, egotistic way of contemplating things is of course harmful.
