So first of all, let's see what 1st house/Ascendant and 3rd house represent -
1st house/Ascendant is your self, physique, personality, overall health, life path and head in human body etc.
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.
One thing to remember here is that 3rd house is 1st 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 1st house lord in 3rd house?
It means the planet which rules/controls/owns the 1st house/Ascendant of your horoscope is sitting in the 3rd house of horoscope.
Now, what is the impact of having 1st house lord in 3rd house?
Its generic interpretation is that person's focus through-out life is on making self-efforts and taking action. It means whatever they gain in life is through their own efforts. None is coming and providing them opportunity. They have to earn their own bread and certainly their own butter. That's why majority of time, this placement is seen in horoscopes of Businessman and Entrepreneurs because they need to make their own earning. It also shows someone's life revolving around his younger sibling.
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 1st house lord is going in 3rd house. So again, Overall Chart Reading is important.
But again, this generic interpretation can also change as per the planet which is going in 3rd house as 1st house lord.
So, let's see how different planets will behave differently as Ascendant Lord in 3rd house.
Sun - Suppose it is a Leo Ascendant chart and Sun sits in the 3rd house in the sign of Libra. Guess what? Sun is Debilitated, specially if it around first 15 degrees of Libra. For the majority of 1st half of life, this person will have lack of confidence. He will always feel that he didn't get the fair results of his efforts. He will also have a feeling that his younger siblings are of not much help. In this case, person will come in to Business World only in 30s when 3rd house as an Upachaya House starts giving good results. Relationship with Father may suffer.
Moon - So it is Cancer Ascendant Chart and Moon rules the 1st house and sits in 3rd house. It shows a person who is emotionally attached with his siblings. It shows that a person has very sibling like relation with Mother but at the same time, Mother had to go through many trials in her life. It also shows Mother or Younger Sibling either being in healing field or has longtime ailments themselves.
Mars - Mars can be Ascendant ruler through its two signs. So, let's take both one after the other.
Aries Ascendant - So if Mars is lord of Ascendant through Aries sign and sits in 3rd house in Gemini, then it shows a person very much into writing. He is into writing blogs, being journalist or into Marketing. His life is revolving around his younger siblings specially brothers. It also shows his siblings/male friends are assisting him in his life path. As Mars also rules 8th house for Aries Ascendant and sitting 8 places away from 8th house in 3rd house, it shows a very long life to the person as it means death of house of death, means a very long life. It shows occult as one of the main interests of person.
Scorpio Ascendant - Now if Mars is lord of Ascendant through Scorpio sign and sits in 3rd house in Capricorn sign, then this is the real position of being a businessman because not only Mars is going into 3rd house but it is exalted there. Again, as it is an Upachaya House, this realization of being a businessman will come in 30s. This person can also be in writing work. Here, person gets support and gives support to younger siblings. For Scorpio, Mars also rules 6th house of obstacles, debts, diseases etc. It shows that person has to deal with obstacles coming into the life of younger siblings. As Mars is exalted, this person will successfully deal with all the problems. It also shows someone who crushes his obstacles through his actions and communications.
Mercury - Mercury also can be Ascendant ruler through its two signs. So, let's take both one after the other.
Gemini Ascendant - If Mercury is Ascendant Lord through its Gemini sign and sits in 3rd house in Leo sign, then he is certainly going to be in writing and communication related work. He will be a smart salesman and able to advertise his business successfully. As Mercury is in the sign of Leo which represents authority, it shows someone as spokesman of Government. As Mercury also rules the 4th house through Virgo sign, it shows that their way of communication and business has come from mother. It shows they are spokesman for their homeland and work for betterment of conditions at homeland.
Virgo Ascendant - If Mercury is Ascendant Lord through its Virgo sign and sits in 3rd house in Scorpio, then it shows a person who is very much interested in Occult and things like Astrology. As Mercury is karaka of Astrology and Scorpio is sign of occult, this person can collect huge amount of occult information with them. As Mercury also rules the 10th house of career for Virgo Ascendant, these people can surely be in business of occult. Even their communication with their siblings is related to occult.
Venus - Venus also can be Ascendant ruler through its two signs. So, let's take both one after the other.
Taurus Ascendant - If Venus is Ascendant Lord through its sign Taurus and sits in 3rd house in Cancer sign then this can make someone a very good singer. They have a very pleasant and beautiful way of communicating. Wealth is certainly coming from Speech and Communication. Love life may suffer a bit in early part of life, but will be good enough once person reaches 30s. For Taurus Ascendant, Venus also rules 6th house of diseases and obstacles. So, obstacles may be coming to the siblings, which they have to deal with. It also shows a career in nursing. Career largely depends on Atma-Karaka, Amatya Karaka and Dasha person going through.
Libra Ascendant - If Venus is Ascendant Lord through its sign Libra and sits in 3rd house in Sagittarius then this shows a person who desires a beautiful relation with younger sibling. In matters of love, they look for intelligence of person rather than beauty. Any work related to beauty, conveniences or counselling will appeal to them. Great interest in occult as Venus again rules the 8th house through Taurus sign. Also, these people face sudden events and transformation in related with life of younger siblings.
Jupiter - Jupiter also can be Ascendant ruler through its two signs. So, let's take both one after the other.
Sagittarius Ascendant - If Jupiter is Ascendant Lord through its sign Sagittarius and sits in 3rd house in Aquarius then it surely shows a person who is teacher as Jupiter is Guidance and 3rd house is communication. But here Jupiter becomes Teacher for a higher cause. They will teach things which is in common benefit for all and serves a higher purpose in society. As Jupiter also rules 4th house for Sagittarius Ascendant through its sign Pisces, it shows that they can also be teacher in the field of spirituality, specially in their homeland. It shows a highly spiritual mother and home environment which molded their teachings and communication style.
Pisces Ascendant - If Jupiter is Ascendant Lord through its sign Pisces and sits in 3rd house in Taurus sign then this person is also very much in Spiritual Field of work as Jupiter also rules the 10th house through Sagittarius sign but here earning finance and wealth becomes equally important because it is in sign of Taurus which is a sign of wealth. Here Jupiter will teach everything spiritual to the world but will also take care if his bank balance is fine or not. They can become wealth managers too.
Saturn - Saturn also can be Ascendant ruler through its two signs. If it is Capricorn Ascendant, then Saturn rules 1st & 2nd house both and sits in 3rd house in Pisces. It means he and his wealth both are getting connected with his self efforts. His self efforts should be in creative and imaginative field, hence here they can become novel writers. Any work which is of creative nature and can be done repetitively and for a long duration can fall in here. As a writes, they can write the longest of novels easily. They can also work as editors and correcting and limiting a written content.
If Saturn is Ascendant through Aquarius Sign, then it rules Ascendant & 12th house and sits in Aries sign in 3rd house. And guess what? Saturn is debilitated here specially if it is close to 20 degree Aries. It shows jobs of labor and hard work. It actually means any job they do will require a lot of hard work. Again, till they attain age of mid 30s, they wont feel that they are receiving proper benefits of their labor and hard work.
Rahu - If Rahu is Ascendant Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 3rd house in Aries then 1st of all we need to make sure of Saturn's position as it is the main ruler. Then, Rahu in Aries in 3rd house shows a person who is here to improve his individuality through self-efforts. This is a very empowering individual who will only progress in life through his own self-efforts. At the same time, this means a person who can suddenly get angry and get into violent activities.
Ketu - Likewise, If Ketu is Ascendant Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 3rd house in Capricorn then again we need to make sure of Mars' position as it is the main ruler. Then Ketu in 3rd house in Capricorn shows a person who is blind towards authority, status and government. Through his self effort, he is not looking for achieving any of these things. It clearly shows a person who is not concerned about any authority, anyone sitting over him. Hence, it is better for him to make self-effort. This position also makes them blind towards feelings of their younger siblings.
Hope this covers maximum points and is helpful.
