What the SEVEN's mean

DISILLUSIONMENT OF CHOICES

SUCCESS NOT YET FULFILLED

UNSTABLE THOUGHTS

TRYING TO STAY ON TOP OF THE HILL

In the Tarot seven is a number of odd and usually uncertain dynamics. It typically combines both positive and negative attributes but an overall place of imbalance. Robert Wang says "the sevens show a force transcending the material plane, similar to a crown which is indeed powerful but requires one capable of wearing it." They show a positive result which is dependent on the action then taken and depend much on the element they are associated with. 

Contrast and balance-seeking is the order of the day with the seven's. In the Swords card (called "unstable effort" by the Golden Dawn,) feelings and instinct attempt to be reconciled with the intellect. In the Wands card known as "valor," the undifferentiated attempts to be reconciled with the individual. In the Cup's card, the group mind with the individual mind, and in the Pentacles the immaterial with the material. 

Faith in what we can't see is emphasized while it can not be manifested without solid footing in the reality. It's like the old joke about the fighter in the ring whose mom is in the audience. The fighter is getting the crap kicked out of him and his mom says to a priest sitting next to her, "Father, will you please pray for my son, he's getting killed up there." The priest says, "Well, of course I'll pray for him, but you know, it would help if he could punch." Sevens are always positive but reliant on the choices available.
