Earth is a fixed sign. It indicates a stabilising effect. The condition it refers to doesn’t necessarily need to change.
Earth is, of course, related to the astrological water signs (Taurus, Virgo, Capricorn), and possesses a lot of the same traits – it is grounded, it brings you back to earth and builds upon solid foundations.
Earth energy is all about the practical aspects of life that concern everyone so much. It can be a solid foundation. It can sometimes even be a little stuck in the mud!
The Earth card is associated with Ptah, so if he shows up elsewhere in this reading, consider the possibility of some kind of soul contract that is contributing to this situation.
The card itself shows the contours of the earth and all of the things that grow from it, and the riches that can be mined from it. The Earth card deals with the practical nature of industry, possessions, and money. It can talk about thrift, conservation issues, practical matters, and all things that grow – birds, bees, humans, flowers, everything else. Fertility is also associated with this card.
If this card has shown up to represent your partner, then they are likely to embody at least some of this energy – good with (or at least, interested in) money, concerned about the welfare of the earth, practical, etc.
If this energy runs out of control, sometimes it can show up an obsession with issues caused by idleness, parsimony, and waste. This means that rather than enjoying the abundance of life, your partner may experience dourness, meanness, and miserliness. This may be their own, or it may relate to you.
