Little is really known about the Joker. In truth, the Joker can be any card in the deck that he or she chooses to be. We cannot make relationship comparisons between the Joker and other cards since it holds no place in any of the spreads that define the Life Paths of the other cards in the deck. The Joker is no card and yet it is all the cards in the deck at the same time. The Joker can assume the personality of any card in the deck at will and yet they have no personality that truly belongs to them. Thus, they fall into a unique category in the system of card understanding that separates them from every other card in the deck. Whether this special place is a blessing or a curse is highly dependent upon the individual who possesses this Sun Card. As in the case of the other cards, every trait we are discussing is either used or abused by the individual and the choices that the individual makes are what determines the nature of the life they experience.
The Joker was the Court Jester in days of old that ascended the throne on 'Fool's Day' each year and impersonated the King, and all members of the kingdom. This day, December 31st, is the time of celebration of the New Year and in ancient times the day to make merry and folly of serious natures. The Joker would make fun of everyone in the kingdom and in doing so taught them how to lighten up a little. He could impersonate anyone with ease. Since we don't know which card they are being, it is difficult to make any definite statements about them.
A Joker might be considered the 'Jack of all Jacks'. This would tend to make them very creative, youthful acting and extremely independent. The Joker is part of the royal family and so we find that they are proud and not too fond of being told what to do, as is the case with most Jacks, Queens and Kings. Because of the strong creative urges in the Joker, we find many are attracted to stage or theater. This same creative energy can show up as a dishonest streak in some of them as well. Many are successful musicians or artists. Whatever type of profession they choose, they are independent and want to maintain a certain amount of freedom if they are to be happy and satisfied.
They have the potential to be deeply spiritual, being the card that is often associated with God in the Tarot decks. Beyond this, there is little known about them. As Florence Campbell puts it, "They are a mystery unto themselves".
