We will discuss both the part separately. Afflicted houses & afflicted planets one by one.

Important houses for one’s chart are as mentioned below;
(1) Ascendant – 1st house – Lagna
(2) Kendra House which is also known as angular houses – 1st, 4th, 7th & 10th house
(3) Trikona houses (Trinal houses) – 1st, 5th & 9th house
Now, we will discuss how these houses will become afflicted as below;
1. There is placement of natural / functional malefics in these houses such as Rahu, Ketu, Mars, Sun etc. based on individual ascendants
2. The dispositor of these house(s) will occupy dusthana houses such as 3rd, 6th, 8th, 11th & 12th house in one’s D-1 chart
3. The dispositor lords of these house(s) are placed in the sign of its debilitation in D-1
4. The lords of these house(s) are placed with functional / natural malefic planets
5. The dispositor lords of these houses are placed in the sign of debilitation in the divisional charts
6. The dispositor lords of these houses are retrograde or stationary in the natal D-1 chart
7. The dispositor lords of these houses are combust by Sun in natal chart
8. The dispositor lords of these houses are placed in enemy signs in D-1 chart
9. The dispositor lords of these houses are in infant avastha (0 degrees to 6 degrees) or old avastha (25 degrees onwards)
10. These houses are under aspects of natural or functional malefic such as Rahu, Ketu, Saturn, Mars, Sun etc based on individual Ascendant
11. The dispositor lord of these houses are placed 12th from its house, eg. suppose one has Cancer sign in 4th house and its lord Moon is placed in 3rd house – Gemini sign in any chart.
12. The dispositor lord of these houses occupy 8th house from its sign. eg. Suppose one has Ascendant Scorpio & its lord Mars is placed in Gemini 8th house. Same way 2nd house lord in 9th house, 3rd house in 10th house etc. (In some cases not applicable such as Aries, Taurus, Sagittarius signs)
13. The house is hemmed between two malefic planets. eg. if one has Malefic(s) such as Sun, Mars, Rahu, Ketu, Saturn in 6th & 8th house, so 7th house is getting hemmed between two malefic planets so person’s marriage life will be affected, similarly this is applicable to all house.
14. This can be seen from both D-1 chart & Moon rashi chart.
Now, let us see the parameters for planets to be afflicted as below;
1. Planet is placed in sign of debilitation
2. Planet is either stationary or retrograde
3. Planet is placed in Dusthana houses such as 3rd, 6th, 8th, 11th or 12th house
4. Planet is placed in enemy sign
5. Planet is functional malefic as per individual Ascendant signs
6. Planet is placed in conjunction with functional malefic signs
7. Planet is combust
8. Planet is placed in the own significator house such as
a. Jupiter in 5th house will cause problems related to children
b. Venus in 7th house will become cause of worries related to marriage
c. Saturn in 10th house will cause problem related to career
d. Moon in 4th house will cause problem related to mother & motherly care
e. many more…
9. A planet owning either the third, sixth, or eleventh house will be a bad planet. A planet owning two of the above three houses, will be a very bad planet.
10. A planet owning the eighth house will be a malefic planet, unless it also owns the first house, and is placed in a house owned by it. If the planet owning the eighth house is a luminary, it will be a neutral planet.
11. If a planet owns the second or twelfth house and another house, the nature of the planet will be determined according to the other house owned by the planet, since for the purpose of ascertaining the nature, the second and the twelfth houses are taken to be neutral.
12. A planet owning the second house will have the ability to terminate the life of the native when the longevity has come to an end. Such a planet is called a maraka planet. A naturally beneficial planet that owns the seventh house will be a maraka. This does not hold true for a naturally malefic planet.
13. A maraka planet owning a triangle will first give good results in its period, and may later end the life of the native. Such a maraka may be termed a good maraka.
14. A planet that owns two houses, one of which is a good house and the other an adverse house as above, shall be classified as a good-but-impure planet. It must be kept in mind that in this case if the mooltrikona sign of the planet falls in an adverse house, the planet will have more malefic tendency in it. If on the other hand, the mooltrikona sign falls in a good house, the planet will have more beneficial tendency.
15. The houses of a category shall gain in strength with their distance from the ascendant. Thus among the triangular houses, the ninth house is more powerful than the fifth, and the fifth is more powerful than the first. Similarly, the eleventh house is more adverse than the sixth, and the sixth is stronger than the third, etc.
16. A neutral planet in sambandha with a planet will take on the nature of the planet with which it is in sambandha.
17. A Node of the Moon will give results of the houses the planet with which it is in association owns. The Node will also give results of the house it occupies. The nature of the Node will be influenced by the nature of the planet with which it is associated. If there is no association, the nature will be determined by the sign and asterism occupied by Node.
a. When the Node occupies a house it becomes the most powerful factor in giving the results of that house. Therefore, occupation of an adverse house by the Node will make it an adverse planet for the chart.
b. The Node becomes an excellent planet when it occupies an angle and is associated with the owner of a triangle, or, it is placed in a triangle and is associated with the owner of an angle.
18. A planet is said to be lajjit (abashed) if it is associated with (at least one of) the Sun, Mars, Saturn, Rahu or Ketu in the fifth house. In the major-period or sub-periods of such a lajjit planet the native has to wander aimlessly, his wife and children fall ill and suffer, he is separated from his family, and the native gets confused and worried.
19. A planet in a watery sign having the aspect of an inimical planet and no beneficial aspect is called Trishit. Such a planet in its major-period or sub-periods causes financial harm and disease to the native. If it is located in the tenth house it causes loss to the native through the wrath of the government.
20. It is not bad to have Venus in the twelfth house, Mercury in the eighth or Jupiter in the sixth. However Venus in the twelfth should not be in the sign or navansha of Saturn.
21. A luminary (the Sun or Moon), if hemmed in between malefic planets, gets the power to kill.
22. Malefic planets gain in strength if they are associated with the Moon.
23. If a planet is powerful in a sign it can retain its nature even under adverse aspects. The aspect is also an indication whether the native would act on his own or he will be aided or hindered in his task by other factors. The planets that are beneficial for the chart shall, by their aspect help a matter, those that are adverse will hinder. For example if the owner of the tenth house is unaspected, it means that the native will not be helped or harmed in his profession by anybody.
24. Of the two malefic planets, Saturn and Mars, the latter afflicts the Moon more whereas Saturn is considered a bigger malefic planet for the Sun than for the Moon.
25. If a malefic planet (including the owner of the sixth, eighth or the twelfth house) is located in a sign, the part of the body indicated by that sign will bear a mark, wound or scar. A beneficial planet so placed will make that part of the body fully developed. If the house indicating that part of the body is also similarly afflicted, the native may have serious trouble there.
26. A sufficiently powerful beneficial planet aspected by malefic planets may not give its full good results. A badly placed or debilitated malefic planet aspected by beneficial planets will not give adverse results. It will become neutral.
27. The sub-period of one planet in the major-period of another in the sets of following planets will generally be troublesome:
a. Mars and Rahu
b. Mars and Saturn
c. Sun and Saturn
d. Moon and Mercury
e. Venus and Jupiter
28. Planet marked with an asterisk shall be good only if it occupies its own house:

The list of planets which are good-but-impure or maraka for various ascendants is as follows:

(1) Mood is afflicted (malefic) if it was waning at the time of person’s birth means if one got birth during Krishnapaksh of the month then Moon is malefic or afflicted.

(2) Mercury is very soft planet, if it is placed with malefic, it will become malefic planet & if Mercury is placed with Benefic, it will become benefic planet.

The lord of the 9th house from the 11th house should occupy the 11th house in conjunction with the Moon, and aspected by the lord of the 11th house then this immense and powerful Gaja yoga will be formed in one’s chart.

S/he will command cattle, elephants, and horses; in current scenario of present time, s/he will occupy lots of vehicles, and owner of huge ranch, stable, etc. S/he will be happy, prosperous and rich throughout life.

This yoga is said to operate between the ages of 20 and 29 years. Obviously, this injunction is inconsistent with the statement that the native would be happy throughout life. The 9th house from the 11th house would be the 7th house so that the lord of the 7th should occupy the 11th house from the Lagna with the Moon and be aspected by the lord of the 11th house. The native may be generally happy throughout the life but the exact period during which the yoga may hold sway would be in proportion to the strength of the various planets causing the Yoga and their Dasa and Bhukti (Antardasa) periods. The underlying idea seems to be that when Gaja Yoga is powerful, the native would always gain in his dealings with others. It is difficult to get the examples of the grand Gaja Yoga.

Pushkala Yoga:

The lord of the sign occupied by the Moon (who should be associated, with lord of Lagna) should be in a Kendra or in the house of an intimate friend aspecting Lagna and at the same time, Lagna should be occupied by a powerful planet.

As complicated as it sounds it is easy to simplify it using 3 basic rules

Ascendant lord (ruling planet of 1st house) and Moon should be in the same sign
The ruling planet of the sign where Moon is located should be in a friendly sign or quadrant and should aspect the ascendant. So, if Moon is located in Pisces in the tenth house then lord of Pisces which is Jupiter should be located in seventh house and aspecting ascendant.
Last condition is the first house or ascendant as it is called should have a very strong planet.
Pushkala Yoga in actual practice is full of significance, as it comprehends that Lagna, the lord of Lagna, the Moon and lord of Chandra Lagna should all be powerful.
This yoga will not be applicable to Cancer Ascendants who have placement of Moon in first house(ascendant).
Example of Pushkala Yoga;

This yoga bestows the native with wealth, fame, sweet speech, honored by the King and a lord. S/he has refined speech and is honoured by the government.

All conditions are near impossible in a horoscope. But even if some of the rules comply in a horoscope it is a great thing to have. A strong planet in first house like exalted Jupiter could ward off all other problematic combinations in horoscope, an exalted Sun in first house could bless native with health and leadership qualities, an exalted Saturn in first house produces a great leader while an exalted Mars produces an achiever who is worshipped by masses. Moon and ascendant lord in same sign suggest synchronization of mind, emotions and body.

If Rahu is in 12th and Sun is in 6th so you have Aquarius Sun which is under eclipse by Ketu. So Rahu is in Leo while Ketu is in Aquarius.

So, here we will discuss 12th Rahu first and later 6th Sun and Ketu. Rahu in 12th will make native somewhat away from being social, person may remain aloof or in isolation for most of the time. S/he may develop dislikes towards friends and relatives. Ultimately, one will get exhausted with all the relationship and finally will leave all and may be chances are that s/he will leave native to find out newer friends or relationships somewhere at far distant place, may be at abroad where no one knows him or her so s/he may begin new journey and new life and new relationship. So 12th Rahu takes native far abroad. Moreover, 12th house denotes spiritual path so this Rahu makes native obsessed to be spiritual and will always keen to participate, join, or engross into spiritual organization, or missionaries. This native would love to achieve newer milestone or new heights into spirituality. They always tend to feign themselves as spiritual personality. They may spend huge amount on some hidden societies, missionaries which deal with some spiritual or occult rituals. 12th Rahu also makes native obsessed with body pleasure, sex, and promiscuity. They cannot withstand their physical urges too. They may have troubled sleep too. Their expenditures are sudden and unnecessary. They may be miser in pleasure expenses but waste huge amount of money behind some hidden occult missionaries or some gurus and Babas.

Now let’s discuss about 6th Ketu. This Ketu will always make native careless about following normal routine. They dislike routine and love to do different tasks on daily basis. They may love traveling and cannot sustain longer in one place, one job. They may have some disputes and differences with their boss and co-workers as Sun is eclipsed here. They have some unnecessary ego. Here Sun is very good which normally give success over enemies. But as Ketu is placed, so this eclipsed Sun may cause ego, lack of confidence, weak or poor in daily routine tasks, difficulty to adjust with superiors, differences with boss, disputes with colleagues, and some health issues.

Aquarius Sun is very good but this eclipsed Sun may cause some health issues such as biliary troubles, acidity, flatulence, colic pain, liver issues, stomach pain, eyes troubles, poor sight, baldness, joint and bone issues, teeth issues etc. Moreover, it will make person sceptical on thier friends, spouse and relatives. Person always tends to stay alone and getting peace alone.

Now this entire combination and permutation makes native aloof, loves loneliness, victim of conspiracy by co-workers, and superiors, health issues, person may lack the confidence on relationship and finally land into far abroad foreign land. His or her father could be government employees with good reputation. S/he may get good legacy from his father which can be confirmed only after verifying 8th house dignity.

Overall good.

Stay blessed.
