Mars in the 4th House
  **************************************************************** 
  You work hard around the home and get involved in home repairs and possibly 
  car maintenance. Many people just feel the need to relax at the end of a hard 
  day's work, but you might prefer exactly the opposite--that's when you really get 
  going. Perhaps you develop a great vitality on the domestic front or in your 
  private life. However, this is where your domineering and aggressive 
  characteristics are most readily displayed. You should therefore take care not to 
  let the aggressions that you have built up during the course of the day to be 
  projected onto your loved ones. If you want to release your tensions at home, 
  then do it by digging in the garden or something similar.  

   
  Mars in this house can be an indication of hidden rage and aggression which 
  you should try to uncover and understand. This energetic force may initially take 
  on the form of great anger and manifest itself in volcanic outbursts which 
  surprise you as much as those around you. Once Mars has been released, you 
  may be able to gradually learn to integrate these energies into your personality 
  and to consciously redirect or release them more positively. As a result, you 
  may find a new vitality enters your life. During your childhood it's possible that 
  you had some unresolved experiences with your father. You will need to 
  process them in order to underline your own independence. You have the 
  potential to deal with these issues when you have made your own 
  home-something that you have wanted to do all of your life. However, if you are 
  too impulsive, there may be difficulties experienced when moving house. A 
  well-aspected Mars will suppress some of these aggressive tendencies, 
  particularly if Neptune is involved.
