When someone has his natal Sun in the 12th house, the light of the star will illuminate all that is hidden and may dissolve all possible fears. On the other hand, as the 12th house is ruled by Neptune and the sign of Pisces, the Sun is in a weak placement. This is even more prominent when it is in Cancer, Pisces or Libra; on the contrary if in a fire sign it will preserve most of its powerful traits.
The 12th house is an open gate to the collective subconscious and unconscious. Thus, any planet located inside will give at least some psychic ability, even if it is uncontrolled and not frequent in manifestation. When the Sun is placed here, the case is exactly the opposite. The person will have a strong connection to the deeper realms of consciousness, and this will be frequently strengthened when they pass time alone. Indeed, the Sun in the 12th house is an indicator of seclusion. Usually, it will make someone a loner and the restriction will be imposed by himself and not by others.
Such people can be rather shy, preferring to not be the center of attentions. The Sun in the 12th house can make them secret benefactors; they will frequently help others without trying to take any type of credit for their benevolent actions. Generally, they like being behind the scenes, and if the Sun is ill-aspected it can even project as agoraphobia. They will generally dislike being in large crowds, preferring introspection. If the Sun is placed in a water sign, the native will enjoy passing his lonely time near the sea or a lake, frequently gazing towards the waters as if he is hypnotized. A common pattern appearing for natives with this natal placement is being bullied during their childhood. This is definite to happen if the Sun is aspecting the asteroid Chiron, and can leave a trauma in the child’s soul.
The Sun placed here indicates an interest in psychology and the occult. The native will be playing the role of psychologists towards others even if he is not qualified as one. He will not be receiving something in return, and his advices can be as good as a professional’s. On the other hand, he will rarely implement the same advice on himself, frequently due to the fact that he does not have a concrete perception of his own self. Such types of people will feel themselves more as souls than bodies, and this is the precise reason of forgetting to give to their body the necessary exercise and care. When one has natal Sun in the 12th house he should be careful of what people he socializes with, because they can absorb energies as a sponge. Negative people in their immediate surroundings will be a daily dose of poison. This can be also a reason for their loneliness, which indeed is many times beneficial in order to cleanse from the effects that other people impose with their presence.
Many natives who have their Sun in the twelfth house have a rather weak father, who is either absent or passive as a character. If the native’s Sun has hard aspects, then the father might be a substance or alcohol addict. With a positively aspected Sun, the native’s father is a very good person, but with a totally passive and unsuccessful role in life. He might be very compassionate towards everyone, but totally unable to structure his own life and be a strong parent figure for the native. In extreme cases, this natal placement of the Sun can make the native not know his father. This happens when Sun is adversely linked with Pluto or with Neptune. Pluto can indicate early death of the father while Neptune will build a fog around him; this can create orphans or elsehow make the father unknown to the native.
If the Sun is somehow connected with the career houses, the 6th and the 10th, the native may work in a prison, a hospital or an asylum; generally in all places that restrict other people. In case that the Sun is somehow linked to the 9th house, responsible for religion, the individual might be drawn towards monasteries or other religious places. In some extreme cases, when the Sun is heavily challenged by malefics, difficult transits can even make the native be secluded in such an institution. Of course, this is not the general rule, or else we would have roughly 10 percent of the population being held in places of restrictions.
If you have this natal placement, do not forget that you also have a body. Developing the mind is wonderful, but it needs a strong body to function well and for long. In addition, you should think more about yourself than about other people. You must learn how to love yourself more, in order to love the others in the right way. Selflessly helping everyone is an amazing act of altruism. But just imagine how much more helpful you would be to your beloved ones (and to the unknowns you tend to help) if you are in a stronger position. Rise up and strengthen that Sun!
