The 6th house is the Maha-dushamsthan, servitude, sufferings, victimisation, debts, loans, illness, conflicts, imbalance, karma due, litigation, enemies, broken contracts, stress to marriage, divorce etc is the domain of this house. The physical actual conflicts are seen from the 6th house from the ascendant sign, but the 6th from the Moon is one placement which you should analyse in detail. The emotional aspect of imbalance, which hits harder than the mere physical aspect.
This one house indicates those agents who are emotionally imbalanced, or cause emotional conflicts, make you miserable, those who are jealous or you, cause problems for your emotional security. This house also indicates illnesses of the mother and how the stresses created in your marriage affect your emotional comforts. Moon basically is nourishment, nurture and nature. All things represented by the Moon are eroded by the house located 6th from the Moon.

You know what the Moon generally signifies, but you should first analyse what your Moon signifies in your chart. e.g. for Libra ascendant, Moon is the owner of the 10th house, the profession, workplace and social status. Planets placed 6th from this Moon will cause emotional problems for the things indicated by your 10th house too. You might think this to be rather convoluted analysis, but astrology is only 9 graha, 12 houses/signs and covers all aspects of your life. So analysing a chart is always like this, patterns within patterns.

Here is a framework which you can use to analyse. The full results of a planet are dependent on several factors, like is it exalted, debilitated, in retrograde or forward motion, combust, involved in a planetary war, in the house of its friend/enemy, aspected by malefics /benefics, where are the signs owned by it placed in the chart, etc. Every chart is unique.

Sun is placed 6th from Moon – Here the self-ego creates problems on the emotional front. Your children, students, expressions of creativity create emotional discomforts. You might want to help them but it backfires on you. Or you might suffer because of men who are father-figures or creatively inclined, always egoistic who attract initially but later create persistent emotional issues for you. Recognise the pattern and try to come out of it.

Mercury is placed 6th from Moon – emotional arguments with neighbours, younger age group, traders, siblings, teammates, mother’s relatives, servants. These agents of Mercury dislike you but you desire to help them! The lesson that this 6th from Moon house is out to teach is this, even if you emotionally want to help these agents, they will create stress for you. So a better option would be to keep a safe distance form them and avoid getting emotionally tangled with them beyond a limit. People with this placement if in business should be alert. Either you wont be able to see the big picture and get lost in the details or you will be associated with such people who will cause you stress.

Venus is placed 6th from Moon – Here you have to look out for addictive behaviour. Women will be a source of pain, sisters too. Venus in the 6/8 axis from the Moon can push towards potentially addictive behaviour of over-indulgence in sugary, alcoholic, numbing, soothing, foods/drugs. The mother may be addicted to something. If this chart is of a man, the mother and the wife are always at loggerheads. Arguments on emotional and trust between the husband and wife, if other factors exist can lead to divorce. Finances will be unstable, as the person takes an emotional attitude towards money, also spends money in paying for ‘soothing’ distractions. Here too, if you are involved in business, be alert.

Mars is placed 6th from Moon – emotional anger and confrontations. Agents of Mars, brothers and brother-figures especially are a source of stress. In helping these brothers, the native gets into emotional trouble. If you have Mars located 6th from the Moon remember that the closer you are to your ‘brothers’, the more you will be stressed emotionally. Then Mars will create aggression, arguments which will make the situation worse. Accept that you cannot help him and be free yourself. If in this, Mars is retrograde, the turmoil you go through is not expressed outwards in a healthier way it gets internalised and you suffer more. This placement can also indicate emotional stress because of boyfriends.

Jupiter is placed 6th from Moon – Jupiter expands thus there will be several emotional issues in life. You will be overweight. This is because you are under emotional stress from so many people in life that you put on fat as a protective barrier, you may over-eat or not eat much but still you will be over weight! All agents of Jupiter cause stress, so the spiritual-teacher, peers, patrons, seniors, demands from your ancestral spirits, even the philosophies that you live your life by, etc will create stress. If this is a woman, the husband creates a significant chunk of stress, e.g. he may be ill, or takes bad decisions etc. This stress is not primarily physical, it is emotional and mental which later filters into the physical body. This placement also confers a workaholic nature on the native, he works and works to fulfil the never ending demands made on him by everyone. If you have this placement think on how much you give to others and how much you give yourself,

Saturn is placed 6th from Moon – this is a difficult placement as the mother is primarily affected due to which the childhood is affected. Perhaps the mother was over-worked, over-burdened, low in the social order etc thus had no time for child-care. Things do get better after Saturn matures at 36yrs of age but life is burdened by a list of responsibilities and duties. There will be demands from the public, you will be required to cater to the society at large, especially to classes lower than yours. You will never feel emotional satisfaction. The body and mind is tired always, there might be an undercurrent of fear. You are afraid to explore emotional ways of releasing yourself and prefer to work instead. Vimshottari periods of Saturn-Moon and Moon-Saturn will be troublesome. If you can cultivate a pragmatic and sensible approach some of these strains can be reduced.

Rahu is placed 6th from Moon – this should be analysed with some caution, as Rahu (and Ketu) take on characters of the planets aspecting/conjoint them and the house owner’s qualities too. Rahu is the rule breaker and the agent who sneaks into privileges rather than honestly earning them. He thrives in the environment of the 6th. He can use the problems of the 6th in imaginative, unbelievable ways to gain. But he always gives body pain. The stress of the wild, unpredictable Rahu, 6th from Moon, who desires stability and cyclic predicable routines, causes internal conflict. Moon wants to nurture and nourish but Rahu drains this Moon completely. There are several unending constant demands made on the personality to ‘give’,which ultimately gives a constant body pain. Moon-Rahu, or Rahu-Moon Vimshottari periods will be especially stressful.

Ketu is placed 6th from Moon – Ketu is scattered and diffuse, so here you are unaware of the emotional stress created by the 6th. The mind ignores people/environments which cause emotional turbulence. Is a rather good placement in a way. There might be pains and troubles in the physical body but the emotions are not affected. But if the lord of the 6th house is powerful then Ketu will take on his influence and give his results as per this planet’s nature.

The Vimshottari Mahadasha period of the owner of this house, 6th from Moon, is always emotionally turbulent. But if you are aware of what is happening you can better cope. So during this period you can expect conflict in your emotional/astral / subconscious / astral bodies / inner depths which will soon filter into your physical body as pain. Depending on the nature of this planet, you will experience internal pain first as a result of arguments, betrayal, treachery, broken promises, unfulfilled expectations, accusations and similar negativity. Some new agent linked to this planet may enter your life then cause emotional stress. (eg if the Moon himself is the owner of the 6th house from the birth moon, it will be a maternal figure). You take care of others but no one even asks if you are tired! You subconsciously expect this to happen and does happen. You are overworked emotionally perhaps victimised and ultimately exhausted. You expect emotional support/validation which doesn’t happen. However if you become aware of this emotional exploitation it loses its sting.

In my opinion, it is best if this 6th house from the Moon remains vacant. If you have a bunch of planets here you suffer more on the internal/emotional levels. The 3rd and the 6th houses of the zodiac are naturally ruled by Mercury with his agenda of arguments and mental loops, the 3rd house from the birth Moon is also a source of emotional stress where your thoughts loop.

The solution is ultimately awareness, if you can be aware of things, you can intelligently manage them, else you remain a puppet in the control of circumstances.
