Mars(Mangal) in sixth House
This house belongs to Mercury and Ketu. Both are mutual enemies and inimical to Mars also. Hence Mars in this house will keep himself away from both. The native will be courageous, adventurous, lover of justice and powerful enough to set fire into water. He will be highly benefited by the trade and business associated with Mercury. His pen will wield more power than the sword. If Sun, Saturn and Mars are placed together in one house, the brothers, mother, sisters and wife will be affected very adversely.
