As Anaïs said, a seed is the perfect symbol of the Ace of Pentacles to me. In truth, I often say that of all the Aces, but when it comes to this suit, I mean it very literally. As the first cards of the four suits, they are often described as the pure energy and potential of a suit. A divine spark; a drop of springwater spilling from underground rock; the first gust of wind clearing the sky. They carry the information, memory, blueprint and fuel needed to sustain their growth. We have the choice to do with that what we desire.
