If the ruler of the 7th house is in the 6th or 12th houses, or if there is an unfavorable position of planets in the 7th house, this may indicate defects in the western part of the home: a western entrance, strong winds from the west, a water source or underground water in the west, a balcony or large open spaces in the western part, a downward slope of land to the west, a courtyard in the western part, and even a blocked eastern direction.
If Saturn is in the 7th house, there should not be defects in the western part, as the west is Saturn’s sector in the home. But if Saturn is in a bad position in the horoscope, this may contribute to defects in the western direction.
Northwest
A northwest defect is possible if there are problems with the Moon in the horoscope or if there are problems in the 5th and 6th houses.
If the ruler of the first house is in the fifth house, there will be doshas in the northwest of the home.
North
According to astrology, the 4th house represents what happens in our home. It is very important for this house of the horoscope to be harmonious in order to prevent the possibility of severe doshas in the home in general, and in the northern direction in particular. Problems in the 4th house may indicate that the home likely has a staircase rising to the north, a southern entrance, a blocked north, toilets facing north, or an east–west axis longer than the north–south axis.
One of the ways to improve the northern sector is for the 4th house to receive a good influence from the Moon. A poorly placed Moon, as well as association with Papagraha (malefic or enemies of the Moon – Mars, Saturn, and the Sun, or heavy aspects, or any negative conjunction of certain planets), contributes to the home not being aligned with the cardinal directions.
To avoid harming the 4th house, it is better not to live near religious buildings, as this may bring curses. In the ancient Vedic period, religious buildings were constructed in specific places in the city so that there would be sufficient distance between them and residential homes. One must ensure that the gates (or entrance door) of the home do not face a religious building, and that the distance between them is at least 25 meters.
Three nakshatras ruled by the Sun (Uttara Shadha, Uttara Phalguni, Krittika) are not favorable for the 4th house. If a person inherits a home under these influences, they will not find peace.
Planets in debilitation in the 4th house do not bring good even if they are benefic by nature. In general, if damaged planets are located in the 4th house, this indicates that the person must likely repay debts to the planets from a past incarnation.
A conjunction of Mars and Saturn in the 4th house contributes to the appearance of debts in the family, and a conjunction of Saturn and Rahu in the 4th house may indicate the presence of evil spirits in the home. In any case, such a conjunction may also indicate a dosha in one or both of the directions governed by each planet.
If Rahu and Saturn are in the 4th house, or if the Moon and Rahu are together in the 4th house, or if Ketu is in the 4th house, or if Ketu is conjunct the ruler of the 4th house in any house, or if Ketu is in the 6th, 8th, or 12th houses, this may indicate a serious Vastu dosha in the home. Also, if Ketu or Rahu are conjunct a malefic planet in the 4th house, this may indicate that a person will live in a very old home, approximately 60 years old, and that it will have certain doshas.
It is said that if Gulika (the son of Saturn) is located in the 4th house, a person may become homeless, a wanderer, unable to be happy and unable to travel.
Northeast
A northeast defect is possible if there are problems with Jupiter and Ketu in the horoscope, or if there are problems in the 2nd and 3rd houses.
