Jupiter is known to be the grand benefic, illuminating any house it is natally placed. When it is positioned in the 4th house of a natal chart, it will generally bring a happy childhood in a large and prosperous family. As the 4th house is traditionally ruled by Cancer and the Moon, the mother will play a very important role in the native’s life, providing him with a lot of love and security.
Jupiter in the 4th house signifies a large family; there are possibilities of having a lot of siblings or living in a large house with a lot of family members; grandparents, uncles and aunts, cousins and even distant relatives. This placement usually gives a lot of wealth to the family, and brings an abundance of food; there is constantly something being cooked and offered at the table, and the whole family eats together in a happy atmosphere.
With such a Jupiter placement, the mother of the native is the archetype of “the provider”. She will cook and feed all the time, even force to eat but in a funny and gentle way. She might be rather fat but also funny, and maybe is the even the head of the family. Her character is strong and fair, while she will usually have a very strong Jupiter/Sagittarius emphasis in her natal chart. Usually, she will be somehow involved in religion and has a high-level perception of philosophy, even if it can be rather abstract. There is wisdom in her, and this will also pass to the native.
The overall childhood is a happy period for the chart owner; there is a lot of fun and playing, while the native observes his parents being happy and prosperous. Family as a term receives a rather positive color in the native’s mind; he will probably dream to continue the same pattern and create a large one himself. Jupiter is an expansive planet, and when natally located there will be pressing the native to expand his 4th house issues during all of his life. The native might want to make a lot of children, and will definitely strive to have a large house as the one in which he spent his early years. It is a very frequent phenomenon that this house will come as a heritage to him after his ancestors pass away. In addition, he can also inherit large parts of land; all the matters concerning real estate, land ownership, agriculture and mining will turn out favorable.
Of course, as Jupiter is the planet of expansion his effect can have even an adverse nature. The native who has Jupiter in the 4th house can be a spoiled child, or be the favorite one among his parents and relatives. The wealth coming from the family might make him lazy, as he could even not need to work in his life because his parents will have provided him with everything needed. Such kind of people may have a big passive income from their early years, and simply live their life with the money that their wealth generates. Is that a bad thing? Of course not! Everyone wishes to be able to live such a life. The bad thing is that the native might spend his life caring too much about feeding his lower needs, without investing in his soul. In case he understands that there are more things in life than having a good time, then he will become really happy and evolve to a conscious being. And this is exactly what Jupiter wants, empowerment of the 9th house- the house of philosophy.
When the native will energize his 9th house, and start concentrating on his spiritual evolution rather than his wealth, Jupiter will manifest in an even better way. Not only he will generate a more prosperous life, but also grant wonderful old years. The 4th house is responsible of one’s old age, and an active Jupiter will make the native receive all the benefits; his last years will be very pleasant. Jupiter gives also a possibility of getting involved in religion- or some other type of moral system/philosophy.
Generally, people with such a placement are advised to not change their residence location; they will not prosper anywhere else in the world as they would prosper in their birthplace. This, of course, happens if Jupiter is well-aspected. Most of the times though, the person with this natal Jupiter is rather complacent and has no desire to relocate somewhere far. After all, the leisure that his home conditions provide cannot be easily found elsewhere, and the mother’s food is also a main reason to stay.
