On the Qabalistic Tree of Life, the Sevens are attributed to Netzach (victory) which is very low down on the Tree of life. This is a doubling of the unbalanced nature of conscious energy as consciousness is now descended deeply into illusion while engaged in a frantic struggle with self-identity. Netzach pertains both to Venus and Earth, and the Heavenly Beauty of Venus is now debauched by Matter. The four Sevens bring no comfort as they are the denigration of each element, exposing the utmost weakness in every case.
The Seven of Wands is called Valour, which may sound charming on first blink; However, Valour is shown only when one knows it is a lost cause that they are engaged in, but continue the fight anyway. Energy is being felt in its last gasp while struggling desperately, it still is easily overcome.
The Seven of Cups is called Debauch and is one of the worst ideas one can have. Debauchery is poisoned thought that produces madness. It represents the delusion of alcohol and drug addiction which is just a process of sinking into the mire of false pleasure. One sees life as pain, and wishes only to live in delusion. You might say that there is something suicidal in this card because of its great weakness, without even a strong planet to balance it. Venus is turned against Venus and Earth is churned into a scorpion morass.
The Seven of Swords is called Futility and is even a weaker card than the Seven of Wands. Its ruler is the Moon, and is a passive planet and passive sign. The little mental energy that the Seven of Swords maintains is just filmy dream work and cannot sustain the labor necessary for the fruition of endeavor. The Seven of Swords is Futile, because the perspective one is holding on to can only give the illusion of performing if encased in a denial of irresponsibility.
The Seven of Disks is called Failure where even dreamy thought has collapsed. Disks, are the suit of extreme passivity (where matter is most solid) and there is no positive virtue in passivity below the Abyss. Careful examination of the Cards and the Tree of Life will clearly explain this statement.
The Seven of Disks is ruled by Saturn and there is no effort here, all is lost and everything is sunk in sloth and all labor is abandoned.
These cards are most depressing, and if the explanations are combined, describe a most disturbing depression, of Energy, Emotions, Mind, and Body. Luckily, I have never seen all of them fall together in a reading and usually other surrounding cards show a lightening of effect and a temporary experience. However, that being said, the Querent should be told that depression is being experience or soon will be (depending on the position of the Card) and to prepare themselves in order to " Weather the Low period". If we are searching for a positive to these Sevens, one could say that without a doubt, an old perspective is dying so a new one of better performance can be created. Sometimes it is hard to let go "of the monster you know" rather than face an unknown. Courage and strong Character dictate that you must.
