Mars in the 8th House 

  You like to do research, which may involve areas such as finance, insurance, 
  and mysticism. You may get into the swing of things through activities with other 
  people's finances, where you can give all you have, but still get much in return. 
  With Mars in this house, it is possible that you will encounter certain feelings 
  like envy, greed, or jealousy in yourself or others. Whether you find it necessary 
  to transform any tortuous emotions into more positive forms of expression 
  depends to a large extent on the aspects of Mars in this house. It would be 
  beneficial to concern yourself with the techniques of relaxation and meditation, 
  particularly as you have a strong interest in the supernatural. However, you 
  should exercise caution when investigating or experimenting with such things.  
   
  If Mars here receives challenging planetary aspects, difficulties may occur with 
  your partner or business partnerships when there is a question of common 
  property. Therefore, a certain degree of caution would be advisable. As Mars in 
  this area has a more subtle influence than usual, you should avoid letting 
  yourself be pulled into whirlwind financial deals. On the other side of the coin, 
  you may defend your convictions by trying to challenge or manipulate those who 
  do not share your views.  
   
  This position of Mars is often accompanied by strong sexual passions, which 
  may be used merely as a means to release physical tensions. Try not to allow it 
  to become a form of competition, in which you would like to feel superior. 
  Lovemaking will have its ultimate expression when made from the heart.
