The Knight of Pentacles is also referred to as the Lord of the Wild and Fertile Land and the King of the Spirits of Earth and represents steadiness, masculine sensuality and honesty.
He is stoical, steady and slow to action but is very grounded and practical.
Knights are about movement and progress and while the Knight of Pentacles appears to be not moving as quickly as the other Suits, move he does. This means that he is more considered and deliberate in the movements that he brings to you, so any movement is well-considered and therefore more successful and long-standing.
As person he is ambitious, thoughtful and patient and leans towards the conservative. He knows that anything worth doing is worth doing properly and so will take his time about any enterprise he sets his sights on.
He may be considered somewhat dull compared to the fiery Knight of Wands or the flashy Knight of Swords, but he is in it for the long haul and his quiet exterior hides a smouldering passionate nature that has much stamina.
On an abstract level he represents goals, plans and practical actions that need to bring any dream into the physical realm. He also represents the body and health, and when he appears in a reading is a sign that one needs to pay particular attention to diet, exercise and healthy habits, particularly the reduction of stress.
Since the Pentacles refer to the material realm he can also herald positive changes to one's investments and securities, and he always counsels caution in with money and other material resources.
It is time to become comfortable and conversant with the practical aspects of life - money, property, investments. What you have been steadily working towards is about to come to you, especially if the results have been slow in coming.
Time to take physical action towards your desires.
