Jupiter rules the Zodiac sign of Sagittarius. It is also the traditional ruler of Pisces. When Neptune was discovered it became the modern ruler of Pisces.
Jupiter is the first of the Generation Planets, which have much slower cycles. The cycle of Jupiter through all 12 signs of the Zodiac is 12 years. This means that Jupiter spends 1 year in each Zodiac sign. All people born in a particular year have Jupiter in the same sign, whereas their Personal Planets (Sun, Moon, Mercury, Venus and Mars) will be in a variety of different Zodiac signs.
Because Jupiter stays in one Zodiac Sign for a year it tends to influence the type of behaviour that will be an underlying pattern in a general sense, where everybody is concerned for that year.
As Jupiter has 12 year cycle, it means it will return to the same position it had when a person was born, every 12 years. This represents the beginning of a new 12 year personal cycle. This occurs for the first time at 12 years of age, then 24 yrs. 36 yrs, 48 yrs. 56 yrs, 72 yrs, 84 yrs, 96 yrs etc.
When Jupiter does begin a new cycle, there is a sense of being on the verge of a whole new era in life. One can look back and see that much of what has taken place in the previous 12 years is drifting into the past and is to be left behind as one ventures into situations with some sort of new meaning. One is usually glad of this but sometimes there is sadness also.
The first 3 years of a new Jupiter cycle are very personally orientated and quite experimental. There is no need to be terribly serious. It is the 4th year where there is a need to establish definite patterns. These patterns set the tone for the rest of the cycle.
Each year within the complete 12 year cycle, Jupiter has an altered mode of activity. This is an extremely accurate indicator of what will be the main focus in any individual’s life during that year. This shows whether it is a year to begin afresh, a year when one can afford to be carefree, a year to stick with what is already established in life or a year to begin winding things down. When a person knows what part of the cycle they are experiencing and they go with the flow of that mode of activity, they will experience a sense of inner peace. With this comes the experience of successfully coping with whatever is presented in life. This could be gaining the ultimate but it may also be learning to gain control of something that hasn’t been so easy. Either one of these experiences will be a victory.
Jupiter is called the “lucky planet”, mainly because it has an expanding quality and luck is always associated with something growing or developing in a favourable way. Jupiter’s expanding quality may also increase the “not so good” and when this happens, it will not seem like luck at all. It will lead to eventual benefit though.
Jupiter’s nature is basically optimistic and stimulates a positive attitude. Optimism is a good thing, provided one has taken the trouble to be well informed. Jupiter does not care what it “grows”. It will grow results of carelessness just as profusely as it will grow results of being well informed. The choice is entirely with each individual.
