Saturn in the 12th House
  ***************************************************************** 
  Twelfth house Saturn with afflicted planets would epitomize karma with oneself, 
  in that you are your own worst enemy. It is a very emotional karma, indicating 
  self-destruction and an afflicted subconscious. This placement has much to do 
  with lessons concerning emotions. You may brood silently over lost 
  opportunities. There can be difficulties from unknown people, institutions, and 
  hospitals. You may sense some responsibility that is hidden away. You may 
  have a fear of all that lies beneath the surface of your consciousness. You feel 
  that you could be swallowed up by overwhelming feelings if you let go of the 
  strict control you have over yourself. The idea of becoming involved with 
  something greater than yourself makes you uneasy. The thought that your 
  individuality could disappear fills you with fear. Due to isolating yourself from 
  others in previous lifetimes, there is an unconscious desire to make restitution, 
  but it is often consciously rejected. Should you decide not to serve humanity in 
  some way, it is highly likely that you will suffer chronic health problems. If you 

  feel that you can break down these feelings of guilt through providing service to 
  others, you may choose an occupation at a hospital, a charitable organization, or 
  any institution which is concerned with serving the needy.  
   
  More often, it is not somebody else who is trying to make life difficult for you, it 
  is you who makes life difficult for yourself. If you continue to isolate yourself in 
  an attempt to forget your dreams, you should perhaps try shore up your 
  self-esteem because only then will you find an inner peace and be able to sleep 
  peacefully again. You may feel that you can only develop your independence by 
  withdrawing from the company of others, or you may fear that everything you do 
  will end in disaster. If you experience these fears in terms of commitments to 
  people, you should carefully unveil and examine your subconscious need to 
  flee. Dissolving the fog and recognizing your purpose will provide rich rewards. 
  Not only will you find subconscious or forgotten aspects to your personality, but 
  you will also develop a feeling of oneness with the world. In the end, the positive 
  characteristics of Saturn will emerge-an ability to recognize your own limitations, 
  an acceptance of duties and responsibility, and a tangible, practical sense of 
  how to help out in a difficult situation.  
   
  In conclusion, Saturn in the twelfth house infers a serious confrontation with all 
  areas of your subconscious being; it is very important to find your own truth. 
  Without any challenge imposed on Saturn, much of this description may be 
  neutralized. If Saturn is well-aspected, you could play a responsible and 
  satisfying role in providing assistance or service to others.
