Symbolism & Imagery:
The Pentacle suit is aligned with the element of Earth, and thus with the zodiac signs Taurus, Virgo, and Capricorn. The Earth element, and by extension the Pentacles suit, is about manifestations in the physical realm.
While it can and often does refer to material goods and money, it is better to look at the Pentacles as covering resources as a whole. Not all of our resources are tangible, and yet they can be used to bring about a better life for ourselves – think of skills you have learned, or support you can give. People in our lives can even be a resource, and we can be a resource to other people.
Think of the person at work with a particular skill set, who you go to when you need help with a problem in that realm. These resources are nonetheless valuable in our lives for not being tangible objects.
