Jupiter in the 10th house is considered to be an excellent placement. The 10th house in our ascendant chart governs the prospects of job, career, business, social respect, relations with the government, health and wealth of the father, promotions, reputation, etc.
A well-placed Jupiter in the 10th house suggests that the person will do quite well in business or if they have a job, they will be famous for all the right reasons. Jupiter in the 10th house also suggests that the person will have a good relation with the government, or that they may be a government employee themselves (though for this, the placement of the Sun and the Moon need to be checked as well).
Such individuals will also do well if they were to open a restaurant or eatery or any business that concerns food; if they are in some job, they will grow steadily on the account of their accomplishments and also be known as someone respectable and dignified. If they are in a job or freelancing or consulting business, they will likely do well in any kind of high-level managerial or executive position or may regularly interact with high-level people.
In business, if such people keep their ethics and morals over their greed, they will be dignified well and may also be known for their ability to perform religious rites which will bring them fame and renown. Here religious rites would also likely mean focusing on ceremonies and establishing religious and Dharmic events that would cause others to know about their capability and help them spread good name and positive reputation about them.
In case Jupiter is in debilitation or afflicted, the person will have immense knowledge and wisdom as well about their career, but they will become famous for the wrong reasons. Such individuals will either try to commit ill deeds or they will have a notorious reputation. If this does not happen, the person’s good deeds will end up being overshadowed by others or they will not receive the recognition for their work. It is also possible that the native’s father may not have a decent reputation in their society or public.
Since Jupiter’s 5th Drishti or aspect falls upon the 2nd house from the 10th house, it is important that Jupiter must be well-placed in the 10th hour or else the income of the person will also be affected.
Jupiter in exaltation in the 10th house will make the person far too inclined towards their father and may cause their relations with the mother to be affected. Such individuals will likely be more focused on religious and Dharmic activities rather than doing business unless Mercury conjuncts Jupiter here. However, they will command considerable influence.
