The Buckle of Isis upon which this card is based, was a carving that was said to represent a womb. It does rather look like one. And the emotions and concepts that are attached to it convey the same meaning.
It suggests growth and abundance in anything – investments, family, money, business. But it also acknowledges that with such abundance, there is typically a price to pay. Be it in energy, or time missed with loved ones or health problems due to overwork. It means that as a couple, you can’t get to what you want without putting in some effort. And bear in mind that it might be quite a significant amount of effort, depending on what it is that you desire.
It does also, however, suggest fidelity and loyalty in relationships.
If you have selected this card as a way to step into your power, then in order to do so, you’ll need to acknowledge and accept that with growth and success, there is a price. Focus on the outcome, rather than the process and then tally up what you will get against what you’ll need to give to get it. If you’re happy with what you’ll need to do in order to get what you want to get, you’ll feel much happier about the whole thing.
