We have, in a sense, already met the four Aces in the Magician card. They are the tools that he uses to manifest his will in the world.
Aces really are amazing. They are like seeds, and like all seeds they are more than just potential. They actually hold within them all that is possible from that particular seed. In the Ace of Wands is all will and passion and inspiration that can exist. In the Ace of Cups, all emotions and all manner of relationships. In the Ace of Swords, all thoughts, all ways of thinking, all systems, all truths. In the Ace of Pentacles, all abundance and prosperity of the physical world.
Aces are often illustrated with a disembodied hand holding the symbol of the suit. This is because we see the Aces as gifts from the Universe. When we are given the gift of an Ace, it is an opportunity. We are handed all possibilities. How we use it, what sort of Magician we are, determines what will ultimately become of this gift.
