Jupiter in 10th House in astrology shows that all planets except Ketu give good results in the 10th house; Jupiter doesn’t really feel comfortable in the 10th house, especially since its weakest position the 10th sign of Capricorn. Jupiter is about religion, spirituality, and dharma. Jupiter in 10th House in Vedic Astrology is like a teacher or professor, and they usually do not like to work but rather give lectures, sitting in their office, and just studying. Here, Jupiter in 10th house is forced to work in a place where they are forced to use their minds and physical bodies. But in the 10th house, Jupiter makes preaching its profession and finds salvation through it.
The 10th house in astrology shows your image in the outer world, as a place of work and community, as it’s opposite to the 4th house, which is home, your private life. It rules career too, but only holds 30% of the truth about your career. In Greek astrology, they give a major emphasis on the 10th house and its lord or the planet sitting in 10th house to determine your career, but this is not true; why, you ask? Because Greek only relies on 1 chart, your basic birth chart, and sometimes eastern astrologer, too, relies on the same chart. But, there is a bigger depth to this house.
In Eastern astrology, there are many (Divisional) charts that show a detailed analysis of a person’s life, career, marriage, children, health, travel, etc.

Capricorn corresponds to the 10th house. Saturn, its ruler, signifies routine work, and the movable property adds to the active nature of the 10th.
