Jupiter in 6th House.

So, lets see what Jupiter can do in 6th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -

Jupiter is the most benefic planet and it represents all the auspicious things like Knowledge, Wisdom, Law, Guru, Spirituality, Religion, Philosophy, Literature, Elderly People. For a girl, Jupiter also represents Husband.

6th house is 1st of Dushthana Houses (houses # 6, 8 and 12) and 2nd of Upachaya Houses (houses # 3, 6, 10 & 11). 6th house represents things like diseases, debts, obstacles, enemies, disputes, competitions, litigations, under privileged people, pets, daily routine life, colleagues at work place etc.

An excellent placement for being a lawyer, as Jupiter represents Knowledge and 6th house represents Disputes and Litigation. So, it shows a person who uses his knowledge to resolve the disputes of others. It also shows someone in service of under-privileged people and pets through his knowledge and wisdom. It can also make someone a teacher of Legal Matters as 6th house is disputes and Jupiter is The Great Guru. In daily routine work life, he will be treated as a Learned Guru, but as it is one of the Upachaya Houses which grows with time, this situation comes after mid-30s. 

From 6th house, Jupiter aspects the 10th house of Career. It shows a need to know about the right career. 

Jupiter's next aspect goes to 12th house of isolated places and let's connect the dots again. This shows that person likes to share knowledge with foreign people or people in hospitals. 

Jupiter's last aspect is on family. It shows that person needs to learn how to manage family and wealth matters. 

Hope this helps. Thanks,
