Marie Curie’s Mercury is at 6 degrees Sagittarius 38minutes in the 12th house. The 12th house is thought of as the house of what is hidden 0r unclear and is traditionally related to karma, loss,  unknown enemies and even ‘one’s undoing‘.  The 12th house  however, has a feel similar to the planet Neptune and the sign Pisces in which there is a loss of boundaries and energies merge sometimes revealing their true source or configuration. This can make the twelfth house a place where  things can become both less clear and more transparent at the same time. When manifested positively this type of experience can bring empathy, compassion, intuition, transcendence and spiritual service. This is why the 12th house represents spiritual places and retreats like ashrams and monasteries as well as institutions, prisons, hospitals and work done in any of these places.
