Sun - Suppose it is a Capricorn Ascendant chart and Sun rules the 8th house with Leo sign and sits there only. This means that this person gets his confidence when he deals with sudden events and transformations in life. When they go through turmoils of life and then come out of it, then they feel highly confident about themselves. It shows they may be working for Govt Secret Services. It shows father was a big influence in life of person in learning how to deal with transformative events in life.
Moon - So it is Sagittarius Ascendant Chart and Moon rules the 8th house with Cancer sign and sits there only. This shows someone from Medical Field. As 8th house is Urgency and Emergency, Cancer is nourishing & taking care of people, Moon is again Motherly Care, it surely shows someone in medical/nursing field and taking care of someone who is in urgent need. It can also make someone an occult related counselor but mostly they will be in nursing.
Mars - Mars can be 8th house ruler through its two signs. So, let's take both one after the other.
Virgo Ascendant - So if it is Virgo Ascendant, Mars rules 8th & 3rd house and sits in 8th house in Aries sign. This shows a person of strongest will power, who can go through all the turmoil of life without even an impression on face. They can defeat and crush any sudden event of their life. Profession wise this can make someone Physician or Soldier. A good placement of a mentally very strong person.
Aries Ascendant - Now if it is Aries Ascendant, Mars rules 8th & 1st house and sits in 8th house in Scorpio sign. This shows almost similar things. Additionally, they will have all the guts to go through every turmoil of life. They will have courage to dig deep into secrets of life. Here, besides Doctor or Soldier, they can be Occultist. They put immense efforts in Occult side of life. They can face death right in front of their eyes.
Mercury - Mercury also can be 8th house ruler through its two signs. So, let's take both one after the other.
Scorpio Ascendant - If it is Scorpio Ascendant, Mercury rules 8th & 11th houses and sits in 8th house in Gemini. As Mercury represents Communications, this person will expose the secrets but it might not be personal secrets. As Mercury is Karaka of Astrology, 8th house is house of Occult & Serving Other People and Scorpio is the sign of Occult, this all shows that this person can be an Astrologer and serving people through consultations or through teaching Astrology. They may be writing blogs about Astrology.
Aquarius Ascendant - If it is Aquarius Ascendant, then Mercury rules 5th and 8th house and sits in 8th house in Virgo, where it is exalted. Here it changes completely. As Virgo is sign of details, analysis and perfection, 8th house is house of Taxes and Revenues, Mercury here shows a Tax Analyst, Auditor or Accountant. It can also show a Banker or Stock Broker. Basically, anyone who deals with lots of number related data. Both positions of Mercury will give good communicative relation with in-laws.
Venus - Venus also can be 8th house ruler through its two signs. So, let's take both one after the other.
Libra Ascendant - If it is Libra Ascendant, Venus rules 8th & 1st house and sits in 8th house in Taurus sign. This shows someone who obviously has love towards Occult and Mysticism, but who is also very secretive about relationship. This person might be secretly having a love story going on but none would know anything about it. They will gain huge wealth after marriage from in-laws and also share a lovely relation with them.
Pisces Ascendant - If it is Pisces Ascendant, Venus rules 3rd & 8th house and sits in 8th house in Libra. Almost similar things can be seen here. Additionally, they would love to keep a balanced relationship with in-laws. With both positions of Venus, they might be doing any business related with Finance and Wealth where they will manage wealth of other people, like a financial adviser etc.
Jupiter - Jupiter also can be 8th house ruler through its two signs. So, let's take both one after the other.
Taurus Ascendant - If it is Taurus Ascendant, Jupiter rules 8th & 11th house and sits in 8th house in Sagittarius Sign. This person is another potential Astrologer. 8th house is Occult & Mysticism, Sagittarius is sign of Higher Education. Jupiter is Counselor and Teacher. So, this shows a person who is all into higher studies of occult and mysticism and then they work as counselor or teacher of occult for others. They are highly learned and ritualistic people.
Leo Ascendant - If it is Leo Ascendant, Jupiter rules 5th & 8th house and sits in 8th house in Pisces. This time higher education is replaced by Spirituality. They dig deep into Occult and Mysticism and find out the Spiritual meaning of those things. They are known as Spiritual Gurus in world but they are equally good in Occult related matters. Best example here is someone like Sri Yukteshwar Giri, who was Spiritual Guru of Sri Paramhansa Yogananda, but known as the best Astrologer of his time in North India. In both positions of Jupiter, person will have great relation with in-laws and will also receive wealth from in-laws or through inheritance.
Saturn - Saturn also can be 8th house ruler through its two signs.
In either sign (Capricorn/Aquarius) as 8th house lord, Saturn in 8th house (for Gemini/Cancer Ascendants respectively) surely indicates someone who has a very long life. Occult related information will come to them slowly but surely. They will get their Gurus in their 30s. Likewise, relations with in-laws are stressful to start with but slowly improve and get much better after mid-30s. Joint Assets with spouse also will improve gradually. These people can be working in Govt or Law related field in which they have to serve people facing sudden events, so law enforcement or army people who help during natural calamities can be seen from here.
Rahu - If Rahu is 8th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 8th house in Aquarius then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Aquarius in 8th house will transform Rahu as Saturn as Rahu changes its nature as per the lord of sign it is placed in. These people will either have very scientific approach towards Occult & Mysticism or they will have very weird/unusual approach. They can give you Scientific meanings of all Occult practices or they can be complete conman while dealing with such issues. They will have unusual/weird relation with in-laws or in-laws may be in/from Foreign Lands.
Ketu - Likewise, If Ketu is 8th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 8th house in Scorpio then 1st of all we need to make sure of Mars' position as it is the main ruler. Here Ketu becomes peaceful and starts exploring the world of occult. Although, it may not give good relation with in-laws but the person becomes research oriented in occult and mysticism related matters and may become an excellent Occultist. This is one of Moksha Margi position. This gives great intuition.
Hope this helps. Thanks,
