Jupiter - Planet of Luck
Jupiter is the thinking person's Planet. As the guardian of the abstract mind, this Planet rules higher learning and bestows upon us a yen for exploring ideas, both intellectually and spiritually. Intellectually speaking, Jupiter assists us in formulating our ideology. In the more spiritual realm, Jupiter lords over religions and philosophy. A search for the answers is what Jupiter proposes, and if it means spanning the globe to find them, well, that's probably why Jupiter also rules long-distance travel. In keeping with this theme, Jupiter compels us to assess our ethical and moral values; it also addresses our sense of optimism.
Luck and good fortune are associated with Jupiter for good reason. This is a kind and benevolent Planet, one which wants us to grow and flourish in a positive way. Jupiter may be judge and jury, but it's mostly an honorable helpmate, seeing to it that we're on the right path. While our success, accomplishments and prosperity are all within Jupiter's realm, this largesse can, at times, deteriorate into laziness and sloth (Jupiter, at its worst, is associated with weight gain!). More often than not, however, Jupiter will guide us down the primrose path.
Leisure time is also one of Jupiter's pastimes. Sports of all kinds, games of chance, and a stroll in the park with the family pet (Jupiter loves animals) are all ruled by this Planet. Finally, Jupiter often presages great wealth, material and otherwise. This is a good friend in the heavens!
It takes Jupiter about twelve years to circle the Zodiac (the Planet visits an average of one Sign a year). It is masculine energy and rules both Sagittarius and Pisces and the Ninth and Twelfth Houses.
