When Neptune is in the 12th house of a natal chart, it feels at home. The 12th house is the archetypal house of Pisces, and Neptune who is their ruler can only function well when is in his own domain. Even adverse aspects to the planet have their own meaning of existence, and this is awakening him through lessons and allowing him to shine his Neptunian light into the depths of the natives subconscious and unconscious. The 12th house is the house responsible for all the things that are laying beyond the native’s conscious mind, and the ethereal presence of Neptune awakens abilities that are connected with his own deeper layers, but also with the collective unconscious of mankind.
This planet in House 12 is in analogy with her (Neptune=Pisces=House 12), so basically she is normally quite comfortable there, but again it will depend on the aspects. With positive aspects, it is the possibility of having a great inspiration and of sublimating certain things, while having aptitudes for all that concerns the study of the psychic and psychological plan, but also for all humanitarian, disinterested activities, in favor of others. With negative aspects, the position is delicate on the psychic level, with a tendency to flee reality, with risk of imbalance, fears, phobias, anxieties, and perhaps abandonments or betrayals in certain areas, and in any case, the risk of experiencing troubled situations, or the obligation to experience a distance, an exile, etc…. All this can cause psychosomatic illnesses. Note also the great sensitivity to drugs and in particular to sleeping pills, tranquilizers, anesthetics, etc….
With the positive aspects of Saturn it will improve mental strength, with those of Jupiter there will be more dedication, with those of Mars it will be the ability to act selflessly, with those of Venus artistic abilities will be enhanced as well as the ability listening to others, with those of Mercury the mind will be able to count on intuition and inspiration, with those of the Moon the sensitivity will be stronger but well used at the level of creativity, with those of the Sun we find the idealism in the service of others.
With difficult aspects of Saturn it will weaken the mind, with those of Jupiter there will be a risk of lack of realism, with those of Mars it will be the tendency to do too much compared to what is obtained in return, with those of Venus the affective plane can be too idealized with platonic affections or sentimental estrangement, with those of Mercury it will be the difficulty to judge rationally, with those of the Moon the sensitivity and vulnerability will be too strong, with those of the Sun the risk is the lack of reference which can push to compensate by derivatives (alcohol, tobacco; drugs, medicines, etc …)
