A major life event will occur. It doesn't have to be all negative. Mars in the 4th gives much energy and vitality, especially since it will be aspecting your Sun. You may change your place of residence, as the 4th rules the home and all things domestic. The changes might be forceful and upsetting though.
Keeping your energies is very important regardless of the situation. You could start a Yoga program, such as doing Hatha Yoga or Kundalini Yoga every day to mitigate the negative tendencies Mars have. Practicing power meditations are important, as is performing an Aura of Protection daily. This protects us from all destructive forces.
