Today, 4th house lord sitting in 10th house.

So first of all, let's see what 4th house & 10th house represent -

4th house represents your home, home environment, homeland, mother, nourishment, childhood friends, peace of mind, conveniences, intuition 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 4th house lord sitting in 10th house?

So, let's see how different planets will behave differently as 4th house Lord in 10th house.

Sun - Suppose it is a Taurus Ascendant chart and Sun rules the 4th house with Leo sign and sits in the 10th house in the sign of Aquarius. It shows that your parents especially father holds a high authoritative position in corporate sector. You are seen as a person of authority in home land. This can give a good political career. It also shows that Mother is as strong person as his father. But at the same time, Sun is in enemy sign and it burns the house it sits in, so it shows a distant relation with father.

Moon - So it is Aries Ascendant Chart and Moon rules the 4th house with Cancer sign and sits in 10th house in Capricorn. Here, Mother would need to take the role of father for various reasons. It shows that your public image is of a very emotional and caring person. You can be involved in any work where you need to take care of others. So, it gives career in the field of nursing, teaching and hospitality as we are required to take care of others in these fields mainly. Person may find restricted nourishment from Mother.

Mars - Mars can be 4th house ruler through its two signs. So, let's take both one after the other.

Capricorn Ascendant - So if it is Capricorn Ascendant, Mars rules 4th & 11th house and sits in 10th house in Libra sign. In both the positions of Mars here, it will be in Venus ruled signs, i.e. enemy signs, but at the same time it is getting directional strength in 10th house. It shows a person who fights for people of his home land as soldier or police person or a sports person who wins for home land. At the same time, he may have troubled relation with his mother. It also shows someone who is Lawyer in Relationship matters as Mars is in Libra, a sign of relationships, and 10th house is house of Law and Government. It is an average position, not too good , not too bad.

Leo Ascendant - Now if it is Leo Ascendant, Mars rules 4th & 9th house and sits in 10th house in Taurus sign. Similar things can be seen here as Mars is again in Venus ruled sign in 10th house. Additionally, this person will have a very transformative relation with mother or home life. At the same time, he will be protective of his mother and home. In both positions of Mars, person is seen as dynamic and headstrong individual.

Mercury - Mercury also can be 4th house ruler through its two signs. So, let's take both one after the other.

Pisces Ascendant - If it is Pisces Ascendant, Mercury rules 4th & 7th houses and sits in 10th house in Sagittarius. This person is seen as a Counselor in society. Take any problem to him and he will have an advise to give you. His advise will be more on religious or philosophical point of view. They can be seen as adviser, religious counselor, preacher and motivational speaker in society but their advise always has a religious or philosophical touch in it.

Gemini Ascendant - If it is Gemini Ascendant, then Mercury rules 4th & 1st house and sits in 10th house in Pisces, where it is debilitated for which I least care about. Same inferences can be drawn with this position. With the only exception that this time counselling would be more on spiritual level. Good communicative relation with Mother in both cases.

Venus - Venus also can be 4th house ruler through its two signs. So, let's take both one after the other.

Aquarius Ascendant - If it is Aquarius Ascendant, Venus rules 4th & 9th house and sits in 10th house in Scorpio sign. This person carries a pleasant image in society. They can be in any work related with art, decoration, talents and creativity. They can be best seen as interior designer. Only fall back here is that their love relations are always have this roller coaster ride and may end in a very negative way. Home life and relations with Mother may go through transformation.

Cancer Ascendant - If it is Cancer Ascendant, Venus rules 4th & 11th house and sits in 10th house in Aries sign. Here again Venus is in Mars ruled sign. Similar professions can be seen in this position of Venus too. But relationships, home environment and relation with mother will be much better here as sign of Scorpio is not involved here. But these people will assert their individuality in relations, means they won't like their partner to be possessive about them and may be willing to keep their own wealth accounts separate from their spouse.

Jupiter - Jupiter also can be 4th house ruler through its two signs. So, let's take both one after the other.

Virgo Ascendant - If it is Virgo Ascendant, Jupiter rules 4th & 7th house and sits in 10th house in Gemini Sign. This is a natural teacher and philosopher. They are seen as Guru in Society. At work place, people flock to them for advice. They can easily become teachers, philosophers, professors and serve the society with their knowledge and wisdom. Parents become the Guru for such a person. They are highly respected in society.

Sagittarius Ascendant - If it is Sagittarius Ascendant, Jupiter rules 4th & 1st house and sits in 10th house in Virgo. Similar results are seen here. Only addition is that these people have more spiritual bent of mind and give spiritual counselling to people to clear obstacles from their lives. They can be teachers in the healing field too. Relation with Mother and Home Environment is very spiritual.

Saturn - Saturn also can be 4th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 4th house lord, Saturn in 10th house (for Libra/Scorpio Ascendants respectively) shows a person who is most hard working of all. As Saturn doesn't give anything easily in life and now it is in the house of Career, so it means they will never get anything in career unless they put 200% effort. As Saturn represents repetitive jobs, they will be in some job where they do same work everyday and which doesn't require much application of mind. At the same time, as Saturn hits hard at things related to the house it sits in, these people have very distant relation with their father. They also become very critical to their mother. At the same time, they will feel duty and responsibility towards parents. Career wise, it can give career in Law, Govt and Politics etc. They can be in some research oriented job too if Aquarius is in the 4th house.

Rahu - If Rahu is 4th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 10th house in Leo then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Leo in 10th house will transform Rahu as Sun as Rahu changes its nature as per the lord of sign it is placed in. So, it will become much like Sun in 10th house as discussed above but at the same time, Rahu's basic nature of being insatiable will remain there. We also need to remember that Rahu eclipses Sun and Moon. This shows a person who is obsessive for authority and fame in this world. He wants to shine as bright as Sun. He will take up some higher cause as a career to serve society and people, so that he can quickly get fame. At the same time, it causes most troublesome relation with father. Person either has great illusions about his father or he is not at all in company of his father.

Ketu - Likewise, If Ketu is 4th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 10th house in Aries 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.
