6th house deals with themes of health, habit, routine, personal development, soul growth, and work life. 6th house is associated with Virgo, a mutable sign, and is considered a Cadent house (indicating adaptability). The ruling planet of the 6th house is Mercury. Mercury’s relationship to the 6th house (and Virgo) is different than its relationship to the 3rd house (and Gemini). In the 6th house, Mercury is related to the analytical side- analyzing what is needed and discarding what is unnecessary so that one can complete tasks and accomplish goals. The 6th house can indicate how you will react to and grow from conflict/difficult situations. It can indicate how you are in service to others and what personal development comes from how you give yourself to others.
