Once upon a time, some people got together by the name of the Golden Dawn and decided to do some reading of the magical traditions that existed. One of those guys was a person called Aleister Crowley who also referred to himself as "The Beast". Now, as you might presume, a person named "The Beast" might have an agenda. It turns out that Crowley did. Short version: Satan.
One of the things they decided to re-work was the tarot deck. Here is the image that they arrived at for the Ten of Swords:
Looks pretty dire, No? The implications are "everything sucks, you are ruined, go ahead and die."
However, an earlier printing of the Tarot Deck called the Marseille deck has this imagery:
Note the difference. I am going to explain it now.
The Swords are an air element. The ten means "across all spheres of the tree". If you do not know what that means, don't worry about it. It is sufficient to understand it as "completion on all levels of air". This means, in essence, truth or reliable communication. So, if that is the case, why does the Mather's Deck look so dire?
It is because they are allergic to the truth. In the beast system, the truth means exposure which means death. Put bluntly, the jig is up!
A further appreciate of the situation involves understanding that they developed the deck to train anyone who might use it to think like a beast when they think. They used art for that end, and that, it turns out, is the real magic here--the magic of deceit.
Why is it everyone overlooks this? I will give you a hint--the system mostly nowadays loves Beast magic and hates the truth. This is the same thing that was true of the Temple in Israel. People became attached to money and not so much were they attached to spirit. The result? Well, I think you know that story. If you do not, I ain't Paul Harvey.
