The 12th house is a closed house, a house of solitude, immersion in oneself, in one's inner world. A very difficult, complex position for Saturn.
Saturn is our support, our inner core, on which our entire life experience is based. It is the deep foundation that helps a person overcome difficulties and move forward, despite the limitations encountered along the way. And the owner of Saturn in the 12th does not feel this support. They perceive the world as unstable and do not understand what they can rely on.
A person is often constrained and tense inside, experiences a sense of insecurity and feels wary of everything that is happening. It is the Saturn in the 12th house that often gives psychological problems, fears, various phobias. Due to the presence of this feeling of insecurity, a person, as a rule, prefers solitude. Or, on the contrary, they are afraid of this loneliness, but in the end, they are left alone with their fears.
If they have any problems or difficulties, such a person, due to distrust of others, prefers to solve everything on their own.
They often generally avoid working in a structured environment or in the space of any strict rules and laws. But whether they like it or not, life will throw some 12th house situations at them - hospitals (a person may chronically suffer from something and constantly be treated). Or live in some remote place, away from society, for example, in a monastery. Or they may be a prison worker, or someone who is forced to serve a sentence there - we look at additional indications. It may indicate a person who has consciously abandoned social norms and moved from the city to the countryside, and is engaged in their own household. Or moved from a noisy city to a quiet place where they are engaged in their own research or spiritual work, or immersed in the world of the occult. There can be many options, we evaluate the chart as a whole.
The theme of the father is also difficult. Either the father is absent, or he left the family early, or the person may not even know their biological father, or the father may be in prison or work there, or he is a very complex father, with whom there is no interaction, or the person may be afraid of him.
