The Ace of Spades is the most powerful and famous of all the tarot decks. It represents a person's capacity to use their creative potential in spite of overwhelming odds. In many cultures, the Ace of Spades also represents the dark side of human nature - the shameful and sinister side. In its original meaning, the Ace of Spades also represented the blind spot or the hidden side of one's inner self that was not accessible to others. Today, however, it has more complex associations and deeper meanings.
In many cultures, the Ace of Spades also represents many other fearful and negative feelings or concepts depending on the respective context. In many ancient societies, the Ace of Spades denotes evil, mysterious, or even malevolent forces that may be harnessed and exploited by humans. For instance, in the ancient Mayan civilizations, the Ace of Spades was used to represent the Earth, especially the volcano known as the erupting of the K'iche'. The Ace of Spades also represents the dark side of human nature: the instincts and urges to hunt, eat, fight, and kill that are essentially destructive and harmful. In many modern societies, the Ace of Spades also represents financial or social decadence and wickedness; the Ace of Spades indicates excessive debt, financial distress, lack of personal or family accomplishment, a feeling of paranoia and anxiety, lack of confidence, poor health, or a general feeling of instability.
However, the Ace of Spades has much more than its symbolism rooted in history and popular culture. In fact, the Ace of Spades has become a significant part of psychic development for the past several years and continues to serve as an important tool for New Age and Spirituality practitioners. In my classes I like to teach students the importance of being able to read the hidden things in people, and using the Ace of Spades as a focus point in personal development and spiritual growth. While it is not the only card in the deck - the Ace of Pentacles, the Ace of Coins, the Ace of Thorns, and the Jack of cards all play an important role - learning to see the Ace of Spades as a source of positive energy, inspiration, intuition, guidance, creativity, peace, and strength of character helps students make positive changes in their own lives on many levels.
