Jupiter in 12th House

So, lets see what Jupiter can do in 12th 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.

12th house is house of Losses, Expenses, Isolated Places, Spirituality, Foreign Lands, Foreign Companies, Imagination, Sub-Concious Mind, Charity, Donation, Asylums, Jails, Hospitals, Hidden Talent and Secrets of Other World etc.

One thing to always keep in mind with 12th house is that it basically remains the house of losses. So, whichever planet goes in 12th house, even exalted, is in the bucket of losses. Now, to gain out of any such planet, you need to put double effort in things related with that planet.

As Jupiter is knowledge, wisdom and God's blessings and 12th house is house of Spirituality, Hidden Talents and Secrets, this position of Jupiter becomes number one in following the path of Spirituality and Occult. These are highly spiritual beings who find their path in life in Occultism, Psychic, Spiritual Healing etc. They start teaching the world out of their experience that look towards spiritual path in life. They find their mental peace in spiritual realm and meditation. 

From 12th house, Jupiter aspects the 4th house of home and due to the effect of Jupiter's spirituality, they convert their home in to a spiritual place. It also shows the need to learn Meditation. 

Jupiter's next aspect goes to 6th house of obstacles, enemies, debts etc. It shows that they like to share their knowledge in resolving conflicts of others.  

Jupiter's last aspect goes to 8th house of occult knowledge and hidden secrets etc. This shows the need to learn about occult and mystical side of life. 

Hope this helps. Thanks,
