Today, 10th house lord sitting in 3rd house.

So first of all, let's see what 3rd house and 10th house represent -

3rd house - It is house of your communication skills, neighbors, short distance travels, younger siblings, marketing, announcements, collecting information, hobbies and skills, self-efforts, business, courage etc. At the same time, as 3rd house is house of efforts, this house shows that results of this house will come only when person will put lots of efforts for a long time.

10th house represents things like Government, Father, Authority, Fame, Work Environment 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. 10th house is one of the houses normally checked for Career/Work/Duty in Life.

Now, what does it mean to have 10th house lord sitting in 3rd house?

It means the planet which rules/controls/owns the 10th house of your horoscope is sitting in the 3rd house of horoscope.

Now, what is the impact of having 10th house lord sitting in 3rd house?

Its basic interpretation is that this person's work environment is going into Self-Effort and Business/Marketing. So, this is one of the most prominent positions where a person becomes a Businessman. It shows that your work environment involves lots of communications and marketing. It shows that when you work with people, you become kind of Authoritative. It also shows that you may have to travel a lot for work. As 10th house lord is 6 places from itself, it shows that your father becomes kind of obstacle for your efforts. Like, he will always want you to follow his word in your efforts, but this happens only when Malefic Planets are in wrong dignity. Overall, a position where work may be related with Business, Communication and Travelling. It also shows someone going towards his hobbies and interests for his career.

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 3rd house lord as 10th house lord is going in 3rd house. So again, Overall Chart Reading is important.

So, let's see how different planets will behave differently as 10th house Lord in 3rd house.

Sun - Suppose it is a Scorpio Ascendant chart and Sun rules the 10th house with Leo sign and sits in the 3rd house in the sign of Capricorn. This is that position when Father becomes adamant that person should follow his words as Sun represents Father and Capricorn is Law & Order. So, Father is very strict here. But thing is that Sun also represents Soul, so this means that person is also equally stubborn to follow what his soul says. This position shows that your authority comes in any work related with communication. This also shows that you show authority to your colleagues and siblings, so you are not very liked by them. Here, Marketing becomes a tough job as ego of the Sun refuses to bow down to the requirements of Marketing.

Moon - So it is Libra Ascendant Chart and Moon rules the 10th house with Cancer sign and sits in 3rd house in Sagittarius. This shows someone whose work environment is going towards Religion, Philosophy and Law. They are emotionally attached with Religion and Philosophy. These people can be seen as Professors, Teachers and Preachers. They can also become a Lawyer. They can be very popular in their local community as a teacher/preacher. Their speech is filled with emotions/care.

Mars - Mars can be 10th house ruler through its two signs. So, let's take both one after the other.

Cancer Ascendant - So if it is Cancer Ascendant, Mars rules 10th & 5th house and sits in 3rd house in Virgo sign. This one shows someone who is very dominating with speech and try to overpower others. Basically, they fight with communications and as Virgo is sign of Conflicts, it very easily shows a Lawyer. But they are very direct and even harsh with their communications. Similarly, they try to dominate their siblings and people around them.

Aquarius Ascendant - Now if it is Aquarius Ascendant, Mars rules 3rd & 10th house and sits in 3rd house in Aries sign. This is much better position as Mars is in own sign. This person always asserts his individuality through his actions. Hence, these people must work for themselves. If they work under others, they will be known as Bully at work place. Profession wise, it can be anything from a Businessman, Occultist, Lawyer to Doctor. All these professions are getting activated, hence whole chart reading will be required. What this shows is an excellent and dominant communicator and a highly self-willed person.

Mercury - Mercury also can be 10th house ruler through its two signs. So, let's take both one after the other.

Virgo Ascendant - If it is Virgo Ascendant, Mercury rules 10th & 1st houses and sits in 3rd house in Scorpio. Here, work environment is all about communications, and it will be written communications. As Mercury is karaka of Astrology, sitting in 3rd house of interests and in Occultic sign of Scorpio, it surely can show an Astrologer or teacher of Astrology. This person can write books, blogs and Articles over Occult side of life. Relations with sibling goes through real change. Basically, work involves lot of communications.

Sagittarius Ascendant - If it is Sagittarius Ascendant, then Mercury rules 7th and 10th house and sits in 3rd house in Aquarius. This shows someone who takes lots of efforts through his communications to resolve the conflicts of people and bring about a social change. So, we can see Lawyers and Activists through this position, who are part of large social groups, who fight to bring justice & equality to all. Another work totally dependent on communications. Alternatively, these people can work in large organizations.

Venus - Venus also can be 10th house ruler through its two signs. So, let's take both one after the other.

Leo Ascendant - If it is Leo Ascendant, Venus rules 10th & 3rd house and sits in 3rd house in Libra sign. As Venus is in own sign, 1st of all it shows that this person has a very pleasant, balanced and beautiful way of speaking. They can win you over through their speech. It shows someone in a very creative work field. These are people who follow their hobbies and interests as Career. It can be any creative field from Media to Movies to TV to Ads. Any place where your creativity comes to the fore.

Capricorn Ascendant - If it is Capricorn Ascendant, Venus rules 5th & 10th house and sits in 3rd house in Pisces, where it is exalted. This is even better position as Venus is exalted here. So, all the results given above are increased manifold here. Only place where Venus in Pisces suffers is in relations. As Venus is exalted here, they seek for most perfect relationship whereas there is nothing like that. That's where they need to be little realistic/practical. Career-wise, another place where someone follows creative side of life as Career.

Jupiter - Jupiter also can be 10th house ruler through its two signs. So, let's take both one after the other.

Pisces Ascendant - If it is Pisces Ascendant, Jupiter rules 10th & 1st house and sits in 3rd house in Taurus Sign. This shows a very good teacher/counselor as Jupiter is taking the energy of higher knowledge and education to the 3rd house of communication. So, this person can be seen as Guru in his local community. As Jupiter is in sin of Taurus, which represents Finance & Wealth, this very much shows a Finance Planner or Financial Guru to others. This person will be considered as Guide to siblings. People come to him for Counsel.

Gemini Ascendant - If it is Gemini Ascendant, Jupiter rules 7th & 10th house and sits in 3rd house in Leo. Now, Jupiter is in friendly sign, so things are even better. This person takes his Spiritual Knowledge to 3rd house as 10th house is ruled by Pisces. So, these people are seen as Spiritual Gurus/Teachers for people. They guide people through Spirituality and there they get their Authority, as Leo is sign of Authority. They must follow the spiritual path of life.

Saturn - Saturn also can be 10th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 10th house lord, Saturn in 3rd house (for Aries/Taurus Ascendants respectively) is one position where person must follow his own business as career as Saturn limits their ability to work with groups of people or teams. They are considered too strict or harsh to work with others. Hence, sooner or later they do their own work. They never want to speak much but they like to write a lot. When they write, they can write heaviest of books or lengthiest of Articles. Person won't have good relations with younger siblings till mid 30s . From mid 30s he ends up having his own work. So, it happens with delay but it happens surely because Saturn in 3rd house person is never able to do jobs whole life. Sooner or later he has to start his own work.

Rahu - If Rahu is 10th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 3rd house in Cancer then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Cancer in 3rd house will transform Rahu as Moon as Rahu changes its nature as per the lord of sign it is placed in. At the same time, Rahu's basic nature of being insatiable will remain there. Rahu in Cancer in 3rd house basically shows someone who is extra emotional. If they are sad, they will cry like a child, if they are happy then they will throw a party to the whole town. They are highly action oriented. You cant keep them sit idle. They communicate on emotional base. They like to serve people through their emotional counseling/teaching. Basically, they want to serve and take care of people but as Rahu is involved there is a chance of illusion in whatever they do. Like, they may be serving others to cheat.

Ketu - Likewise, If Ketu is 10th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 3rd 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 actually separates person from his siblings, either physically or mentally. They never find the balance in relationship with siblings. At the same time, they remain concerned for their siblings. This person may not be too interested in running a business. They may also not be too willing to travel around. It shows someone who has very spiritual way of communication. They don't like to talk much but when they communicate then it is always in a spiritual way. So, they can do good as Spiritual Counselors. Ketu is in Aries shows that they feel lost of their individuality, like who they are, and they find it either through Spirituality or through Younger Siblings.
