Today, 6th house lord sitting in 10th house.

So first of all, let's see what 6th house and 10th house represent -

6th house is 1st of Dushthana Houses (houses # 6, 8 and 12) and 2nd of Upachaya Houses (houses # 3, 6, 10 & 11). 6th house represents things like diseases, debts, obstacles, enemies, disputes, competitions, litigations, under privileged people, pets, daily routine life, colleagues at work place etc.

10th house represents things like Government, Father, Authority, Fame etc. Here, Authority should not be understood in literal sense, like someone got a Government job or became a Manager or CEO of a Firm. Here Authority means doing any work with complete perfection and your opinion matters when comes to making any decision related to that work, so even a good Hacker can be a person of authority as he is master of that particular work.

One thing to remember here is that 10th house is one of Upachaya Houses, i.e. House # 3, 6, 10 & 11. Upachaya Houses improve with time. It means any planet in these houses improves in results with age and real good result is seen from a person's 30s. Also, all the malefic planets provide very good results in Upachaya Houses but results may be seen in 30s.

Now, what does it mean to have 6th house lord sitting in 10th house?

It means the planet which rules/controls/owns the 6th house of your horoscope is sitting in the 10th house.

Now, what is the impact of having 6th house lord sitting in 10th house?

Its generic interpretation is that 2 houses related with work (6th house is daily routine work and 10th house is career) are exchanging their energy. So, this person will be very much a work oriented or Workaholic type of person. His Career might be related to litigation or healing activities, i.e. either he is an Advocate or Doctor. As 6th house is also related with Competition, the person may be an Athlete too. But overall, these are the most hardworking people.

Now, results may be different due to aspect, conjunctions of other planets or the planet being Retrograde or Combust. Moreover, now we also need to check the strength of 10th house lord as 6th house lord is going in 10th house. So again, Overall Chart Reading is important.

So, let's see how different planets will behave differently as 6th house Lord in 10th house.

Sun - Suppose it is a Pisces Ascendant chart and Sun rules the 6th house with Leo sign and sits in 10th house in Sagittarius. It clearly shows someone who works for Govt or whose Father works for Govt. This person would be working for Govt in field of Law or Administration. This person can be a professor in Law or Philosophy in Govt Colleges. He is man of high learning and wisdom. He is seen as person of authority at work place. His work brings great fame to him.

Moon - So it is Aquarius Ascendant Chart and Moon rules the 6th house with Cancer sign and sits in 10th house in Scorpio Sign, where it is debilitated. If is nearby to real degrees of debilitation, it shows that his daily routine brings transformative situations in his career. It means he might be unhappy about working conditions and he brings up the issue then it gets back fired. It also shows someone in healing work whose work involves lots of research work. It wont be surprising to see these people as Surgeons. They may have a very secretive and mystical image in public. Any other yoga or dasha can change the results completely.

Mars - Mars can be 6th house ruler through its two signs. So, let's take both one after the other.

Scorpio Ascendant - So if it is Scorpio Ascendant, Mars rules 6th & 1st house and sits in 10th house in Leo. This can make a person highly motivated & strong-willed and hence they can be in Police or Defense Forces and serve the Govt as Mars is going into 10th house of Govt and in Leo, a sign of Authority. They can also be a very good sports person as Mars is natural athlete and it is in sign of Leo, which represents being on center-stage. It also gives a great interest in Politics. A real good relation with Father.

Gemini Ascendant - Now if it is Gemini Ascendant, Mars rules 6th & 11th house and sits in 10th house in Pisces sign. This time energy exchange is between Scorpio and Pisces, 2 mystical and enigmatic signs. Now, this Mars is all about Mysticism, Occult and Spiritual Training. So, this person can become a Yoga Teacher, Meditation & Martial Arts Coach. So, Mars' energy of being an Athlete is there but it is getting expressed in a Spiritual or a Unique way. Relation with Father and Authority Figures will be good. This Mars is all about other worldly things.

Mercury - Mercury also can be 6th house ruler through its two signs. So, let's take both one after the other.

Capricorn Ascendant - If it is Capricorn Ascendant, Mercury rules 6th & 9th houses and sits in 10th house in Libra. Clearly shows a person whose daily routine is business, marketing and communication. Gemini is sign of Business, Mercury is planet of Business and Libra is another sign of Market place. So, this person is all about making money through business and communications. Relationship with Father will be very friendly. This person is going to be a very clever salesman.

Aries Ascendant - If it is Aries Ascendant, then Mercury rules 6th & 3rd house and sits in 10th house in Capricorn. This position of Mercury can show a person who spreads awareness and counsels people about health care and healing activities. As sign involved is Capricorn, which represents Govt, it can show someone who is Doctor or Health Counselor at a Govt Hospital. It can also show someone who communicates about disputes and conflicts to Govt or Authority, so it shows a Lawyer or Rights Activist. Both positions of Mercury are good for Career and also give good relations with Father.

Venus - Venus also can be 6th house ruler through its two signs. So, let's take both one after the other.

Sagittarius Ascendant - If it is Sagittarius Ascendant, Venus rules 6th & 11th house and sits in 10th house in Virgo sign, where it is debilitated. If Venus is nearby its degree of real debilitation, it shows that someone may get into some dispute with some lady co-worker at work place and that may ruin his public image. It shows although person earns money from his work but he is never happy with his gains. It also shows someone in healthcare and healing field. For a Man, debilitated Venus will become a karaka of Divorce but the actual event of divorce may need dasha/transit etc to happen. It also shows someone getting into love with colleague at work which didn't result too well. Any other yoga or dasha can change the results completely.

Taurus Ascendant - If it is Taurus Ascendant, Venus rules 6th & 1st house and sits in 10th house in Aquarius. This is much better position of Venus as it is in a friendly sign. This person loves to serve ill & under-privileged people and animals. They turn it into their Career. They do it with some higher purpose in mind for all. They can be seen working in Govt Hospitals as Veterinarian or in Govt Agencies meant to serve poor. Immense love towards Father.

Jupiter - Jupiter also can be 6th house ruler through its two signs. So, let's take both one after the other.

Cancer Ascendant - If it is Cancer Ascendant, Jupiter rules 6th & 9th house and sits in 10th house in Aries Sign. This is again an energy exchange between Jupiter and Mars. This person is seen as Guru or person of high wisdom in Society. People come to them for advice. They know how to clear the conflicts through their Wisdom. Hence, they can be seen as Counselors or Advocates in public. At higher level, they can be seen as Spiritual Gurus who help people with their advises and clear their obstacles with wisdom. A really good relation with Father. Father remained the source of all the knowledge and wisdom.

Libra Ascendant - If it is Libra Ascendant, Jupiter rules 3rd & 6th house and sits in 10th house in Cancer, where it is exalted. This is the best position among all. This shows a person who is helping people in resolving their disputes through their counselling on religious and spiritual wisdom. One chart on top of my head which has this position is of Shri K N Rao, the best Astrologer on this planet right now. So, they are all about counselling and guiding people and resolving their disputes.They are seen as Guru in Public.

Saturn - Saturn also can be 6th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 6th house lord, Saturn in 10th house (for Leo/Virgo Ascendants respectively) shows person had a distant relation with father, for various reasons. It also shows disputes with Father. It shows someone reaching authoritative position in life only after sheer hard work and dedication. Nothing comes easy in life where Saturn is placed. It shows person had real struggle with any authority figure in life. Even a watchman will show him attitude when time is wrong. This shows someone making a career in Law or Govt Administration. They can also become a Judge but all good things related with Saturn comes when they are in their 30s. Before that it is only a struggle to find out why everyone around them has so much attitude over their authority?.

Rahu - If Rahu is 6th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 10th house in Gemini then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Gemini in 10th house will transform Rahu as Mercury as Rahu changes its nature as per the lord of sign it is placed in. So, it will become much like Mercury in 10th house as discussed above but at the same time, Rahu's basic nature of being insatiable will remain there. Rahu in Gemini in 10th house shows a person who is highly communicative at his work place or may be a counselor. As Rahu rules 6th house of illnesses and Rahu itself is Medicines and Drugs, it shows someone in medicine related counselling or business. Alternatively, it can also show someone's daily routine work is at Foreign Countries where Communication is a huge part of their work. There is always some illusion about their relation with their father.

Ketu - Likewise, If Ketu is 6th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 10th house in Pisces then 1st of all we need to make sure of Mars' position as it is the main ruler. As Ketu isolates/separates a person from the things related to the house Ketu is sitting, here it separates person from working under any authority. Relationship with Father is not to talk about. Either they are physically separated from Father or they never find that mental connect with him. It is better for these people to either work for themselves and be their own authority or follow a spiritual career. They are the last people who are looking for any authority over any other. Ketu in Pisces also shows the same thing as Pisces is the only sign where Ketu finds Peace. Hence, way of a Spiritual Career is clear.
