Sun - Suppose it is a Cancer Ascendant chart and Sun rules the 2nd house with Leo sign and sits in the 6th house in the sign of Sagittarius. As Sun is significator of Health and Heart, this position surely shows someone in medical field. As Sun burns the things related with the house it sits in, here it burns out diseases and illnesses. It means these people fight against diseases, defeat them and thereby they earn their wealth. As Sun is also planet of Authority and Sagittarius is a friendly sign, these people gain authority by healing people.
Moon - So it is Gemini Ascendant Chart and Moon rules the 2nd house and sits in 6th house in Scorpio, where it is debilitated. Now, if Moon is near its debilitation degrees then it shows that your family goes through transformative times due to some litigation in which you end up in losing wealth. But if it is far from the debilitation degree, then it again shows someone who is in nursing field, as Moon mainly represents Careers life Teaching and Nursing. What this can also show someone giving services in 8 hours job setup, as mind never feels motivated due to debilitation to take a risk and start a business.
Mars - Mars can be 2nd house ruler through its two signs. So, let's take both one after the other.
Pisces Ascendant - So if it is Pisces Ascendant, Mars rules 2nd & 9th house and sits in 6th house in Leo sign, it shows someone who fights for the rights of under-privileged people through his communication. So, it shows someone who is a Lawyer or Rights Activists. They want to bring balance and justice in society. As Leo is the sign of Government and Authority, they become Government Representatives on these social issues.
Libra Ascendant - Now if it is Libra Ascendant, Mars rules 2nd & 7th house and sits in 6th house in Pisces sign. Here also it shows a fighter for the rights of the other as Pisces is ruled by Jupiter which represents written law but Pisces also represents spirituality. So, these people may also become Spiritual and Motivational Speakers, who try to bring balance in society through God's Word or who try to motivate down-trodden to fight for their rights. With Mars in 6th house, it also opens the doors for the career of Sportsman, as 6th house is house of competition.
Mercury - Mercury also can be 2nd house ruler through its two signs. So, let's take both one after the other.
Taurus Ascendant - If it is Taurus Ascendant, Mercury rules 2nd & 5th houses and sits in 6th house in Libra, again a sign of Justice and Balance. So, here also a person can become a lawyer. As Libra is also sign of Relationships, this can be a divorce lawyer too. At the same time, this can be a person who is providing service in Finance Industry through his communications.
Leo Ascendant - If it is Leo Ascendant, then Mercury rules 2nd & 11th house and sits in 6th house in Capricorn. As Capricorn is sign of Government and Law, .it again shows someone who is using communications to bring justice in society. It is again a Lawyer like profession. . Whatever work this person does, communications remain a huge part of their work, either in service or working on their own. He can be a Govt Attorney too.
Venus - Venus also can be 2nd house ruler through its two signs. So, let's take both one after the other.
Aries Ascendant - If it is an Aries Ascendant, Venus rules 2nd & 7th house and sits in 6th house in Virgo sign, where it is debilitated. If Venus is near to its actual debilitation degree, then it shows that your family and wealth was lost in disputes and most probably in divorce. If Venus is far from debilitation degree, then it shows someone who is inclined to serve in a job setup as 6th house is daily work routines also.
Virgo Ascendant - If it is Virgo Ascendant, Venus rules 2nd & 9th house and sits in 6th house in Aquarius. This is the real person who is just too happy working in job setup in corporate world as 6th house is daily work routine, Aquarius is Large Organisations and Venus is friendly to Aquarius's lord Saturn. So, this person is too happy receiving a fixed income every month.
Jupiter - Jupiter also can be 2nd house ruler through its two signs. So, let's take both one after the other.
Scorpio Ascendant - If it is Scorpio Ascendant, Jupiter rules 2nd & 5th house and sits in 6th house in Aries Sign. So, the results will be akin to Mars in Pisces as in both cases Mars and Jupiter are exchanging their energy. So, another case where you can see a lawyer but this time the speech of person will be very direct and precise. They won't beat around bushes.
Aquarius Ascendant - If it is Aquarius Ascendant, Jupiter rules 2nd & 11th house and sits in 6th house in Cancer, which is exalted. This saves the person from even the deadliest of diseases. As Jupiter represents Biology and Cancer is sign of taking care of people, this placement may make a medical professional and a great one too. In both the cases of Jupiter, their luck increases when they take care of others.
Saturn - Saturn also can be 2nd house ruler through its two signs.
In either sign (Capricorn/Aquarius) as 2nd house lord, Saturn in 6th house (for Sagittarius/Capricorn Ascendants respectively) shows that person has real healing abilities, specially in the sign of Cancer. As Saturn is about Service and 6th house represents under-privileged people, these people become real social activists and servants. In Medicine, they have that healing touch ability.
Rahu - If Rahu is 2nd house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 6th 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 6th house shows someone who earns his wealth through marketing of medicines. It shows pharmacist and medical representatives etc. Any field of Scientific and Technical research is good for them where they uplift the down-trodden with their service/work.
Ketu - Likewise, If Ketu is 2nd house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 6th 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 actually isolates person from the diseases and disputes, means person lives a very healthy life. At the same time, they are almost blind about the place where they are giving services. They have this attitude of being workaholic without seeing if that is helping them financially or even career-wise or not.
Hope this covers maximum points and is helpful.
