The King of Pentacles card is a sight to behold – it's one of the most lavishly decorated cards in the whole of the tarot deck. The king not only sits in the middle of a garden – he IS the garden! Or so his clothing would have you believe. His rich robes are covered in fruit, presumably red grapes. On the stone throne are bull heads, one on each arm and one on each corner of the back rest – the bulls are reminiscent of the Charging Bull near Wall Street. In his one hand a scepter, in his other a coin, he keeps his eyes closed in order to feel the earth around him.
To start with, we'll want to disambiguate court cards. They are often the most difficult to read, due to their general nature. It is easier to remember that a court card often signifies a person or entity: the sex of the person may not match that of the court card, but the attitude and persona will seem familiar. If it's clear, however, that the court card doesn't refer to a person, remember to break it down further. First, define what the suite stands for – e.x. Swords generally refers to thought and intellect. Then take the role of that court card and apply it to the suite – e.x. A Page of Pentacles would be a young juvenile in the world of the material/physical, just as the Page of Wands is the inexperienced lad of action and creativity. This can help you to decide what the court card is trying to tell you.
Person: A King of Pentacles person is not an easy one to miss – chances are you'll know who this individual is if they are present in your life, as they are hard to forget. This king is knowledgeable, responsibly, and competent – you can be sure that he is an expert in his field, and nearly an expert in anything he “dabbles” in. He is dependable to a fault, and never lets anyone down if he can help it. He supports others in their ideas, and tries to help them see how they can bring about physically manifesting their plans. He is a firm rock to build a family upon, as he is surefooted and always supportive of others (as long as they believe in themselves). Above all, the King is an outward manifestation of the Pentacles suite – he looks to help those in his life bring their physical dreams, wishes, and goals into reality.
Metaphor: The King asks for you to take on his role, or to (at the very least) heed his advice. Be supportive of others' plans and ideas, including your own. Never seek to unbalance others intentionally – instead, look to keep them grounded, prepared, and realistic in all things. Assume responsibility when it's yours to take, and don't drop the ball if you can help it. Above all, try to help those around you to see how they can bring what they think, feel, and desire into this world so we can all be blessed by it.
When approaching the King of Pentacles, you'll want to ask yourself a few questions. Does the King represent a person in your life? If so, who? What lessons do they have to teach you? If not, what traits of the King should you work to bring into your own life? Reliability? Stability? Compassion and interest in the wants of others? How about supporting others, including yourself? How can you bring these things into your life on a daily basis?
The King of Pentacles is a unique card in it's particular type of energy, but there are at least two cards that share some of it's factor – the Emperor and the Ten of Pentacles. The Ten of Pentacles features a perfect ending to the Pentacles suite, featuring safety, security, and comfort – the King has all of these things, and seeks to bring them to others in his life, so these two cards match well together. The Emperor plays more to the King of Pentacle's kingly side. The Emperor seeks to rule over all those in his life with a steady hand and lead them to prosperity – while the King of Pentacles looks to help others, he is less of a ruler and more of a guide... but the two cards still pair well.
