9 planets ruling 9 zones of your house

Same 9 planets (including 2 psuedoplanets Rahu and Ketu) which govern your horoscope also govern 9 different zones of your plot/house. For example, North East zone of the house is governed by Jupitor. A zone which is not as per Vastu (e.g. toilet in north east zone) can cause specific issues to the resident of that house.  Vastu is about enhancing positive energy in each zone and from the planets for the benefit of the resident.

Vastu to be checked for the house as well as the plot on which house is constructed.

Since 9 planets are governing 9 zone of the house, treat the plot/house like a temple - 

• Toilet should be built outside the house. If constructed inside the house, only few zones are suitable, check with your vastu consultant on which zone is suitable for toilet inside the house as per your horoscope.
• Discard old/damaged/unused items, most importantly calendar, clock, mirror, stove, photo/idol of the God.
• Avoid heavy items which reduces the positive energy of that zone/planet.
• Avoid black/dark colored items which absorbs the positive energy of that zone/planet.
• Go for natural items - avoid artificial items including metal as much as possible.
• Keep the home clean and clutter-free.

House plan should be most preferably square or rectangle which ensures uniform area for all the planets, otherwise area for some of the planets may be cut, which cuts down energy from that zone/planet.

North East zone is the most auspicious zone, so ensure main door is in this direction. Ensure we always face north-east or north or east while doing any work.
