Like all things, make of it what you will.

So... Robert Anton Wilson was having an ebay auction for a card randomly selected from a tarot deck. For $5, and an autograph from one of my favorite authors, why not?

So I got this card. One of the Major Arcana.

The Devil.

[Cue spooky "woo-woo" music, if so inclined.]

Make of that what you will.

[Or read some standard interpretations below.]


Wikipedia

The Devil is the card of self bondage to an idea or belief which is preventing us from growing... On the other hand, however, it can also be a warning to someone who is too restrained and/or dispassionate and never allows him or herself to be rash or wild or ambitious, which is yet another form of enslavement.

The Devil is the 15th card of the Major Arcana, and is associated with earth and Capricornus. Though many decks portray a stereotypical Satan figure for this card, it more accurately represents our bondage to material things rather than any evil persona. It also indicates an obsession or addiction to fulfilling our own earthly base desires. Should the Devil represent a person, it will most likely be one of money and power, one who is persuasive, aggressive, and controlling. In any case, it is most important that the Querent understands that the ties that bind are freely worn, and you are only enslaved if you allow the abuse to go on.

In Jungian terms, he is The Shadow. All the repressed, unmentioned or unmentionable desires that lurk beneath.

Perhaps the most misunderstood of all the major arcana, the Devil is not really "Satan" at all, but Pan the half-goat nature god and/or Dionysius. These are gods of pleasure and abandon, of wild behavior and unbridled desires. With Capricorn as its ruling sign, this is a card about ambitions; it is also synonymous with temptation and addiction. On the flip side, however, the card can be a warning to someone who is too restrained, someone who never allows themselves to get passionate or messy or wild - or ambitious. This, too, is a form of enslavement. As a person, the Devil can stand for a man of money or erotic power, aggressive, controlling, or just persuasive. This is not to say a bad man, but certainly a powerful man who is hard to resist. The important thing is to remind the Querent that any chain is freely worn. In most cases, you are enslaved only because you allow it.

...This card explores some very frightening things, things we are taught to view as evil or shameful. Like earthy materialism, sexual desire, valuables, food, drugs. Lack of control, excess, obsession and raw ambition. At its absolute worst, this is either the addict or the stalker, totally obsessed, enslaved. At its best, this is a card about giving into impulse, cutting lose, going for the gold, climbing every mountain. Among all the cards, this is one of the most complex. Interestingly because no other card is so one-sided. Most cards urge balance, unity, restraint, yin-yang. Not this card. Completely tilted toward the masculine, it is a card that revels in extremity. There is a convincing argument that this is the most powerful and dangerous card in the deck. Magically speaking, it is the one card in the deck that holds the secret of how to escape the material and temporal bonds of Earth. It is a very potent and fascinating card.
