Sixth house is known as Ari Bhava or Shatru Bhava in Vedic Astrology which literally means the House of Enemies.

Whether a person will have few enemies or a great number of enemies, is seen from this house along with other factors. A clean sixth house would indicate comparatively lesser number of enemies or opponents and accordingly lesser amount of problems created by enemies whereas bad influences of negative planets on this house either by placement or by aspect would indicate a greater number of enemies or very strong enemies who usually cause many problems to the native throughout his life. But this house also represents many other things apart from telling about the enemies of a person.
