Children who cannot concentrate on studies often have a study table that is not level, so the gravitational force on it is not balanced. The same applies to a shop counter and the owner's seat (gaddi).
The dev bhoomi, the third band inward, can take everything the household needs, from the main door, windows and kitchen to bedrooms, dining, puja room and stairs. It is the best place for the puja room, the safe, a study room, a meditation room and all important documents, because this land is covered with divine qualities and makes work succeed.
Nothing valuable or sacred should sit on the pishach bhoomi: never a tijori, court case or other important papers, a child's study table, a bed set directly against the wall, or a deity and home temple. Leaving even a 2 to 3 inch gap from the wall keeps an item off the pishach band.
The West-South-West receives the energy of its opposite zone, the East-North-East, whose playfulness brings the water element and concentration to the neurons and glial cells. It is the best zone for study, and the sun, magnetic field and gravitational force strengthen memory here.
Each planet rules a direction (Sun East, Mercury North, Saturn West, Rahu South-West); if that planet is debilitated, badly placed or very low in degree in a person's kundli, a house facing, bedroom, office seat or study in its direction harms them.
The first principle of interior vastu: identify the element of the person, of the structure being built and of the activity done there, and make sure these elements are friends.
The third principle of interior vastu: furniture, tables, the tijori (safe), artefacts and idols must sit perfectly level and in proper alignment so that gravitational force acts on them correctly.
The house facing, main door and common areas are chosen from the grih swami's (owner's) kundli, while each member's bedroom and study are planned from that member's own kundli.
From 7:30 to 9 am the Sun sits in ESE and its rays churn (manthan), making it the zone of analysis, also called the anxiety zone. It suits wash areas, septic tanks, guest rooms, lifts and rooms of small children or research scholars, but not adult bedrooms, tijori or business counters.
North is Kuber's treasury: Kuber promises to keep the store full but asks for hard work, giving opportunities for work and business, so it is the zone of opportunity and money. Keep the North light, low and open, with water and greenery.
The bedroom must be chosen with the person's horoscope in mind, not by one standard formula. South and WSW are excellent, WSW suits everyone, and every other zone gives results that depend on the planets.
A summary chart assigns sleeping zones by age: children, couples up to 45, adults from 45 to 60 and people above 60 each have their own suitable zones.
A study room needs its door in the NE, East, North or West, cross-ventilation, a correct slope, a perfectly level study table and bookshelves on a North or East-facing wall.
Blue is a natural cooling and antiseptic colour that brings devotion, truth and respect, keeps body temperature balanced, and gives mental peace and spiritual growth.
The house as a whole is planned from the chart of the head of the family whose money built it, while a member's own room can follow that member's chart.
If a house has four members, whose kundli should be used for its vastu?
Primarily the grih swami's, the person whose money is going into the house, because the house affects the owner and his next three generations; do not go by the name the property is registered in, such as a daughter. The facing and main door are chosen from the grih swami's chart, for example North if his Mercury is exalted or his North-side planets are strong. Where a child sleeps or studies is decided from the child's own chart: if the child's Mercury is weak, seat him in the South instead of the North, following the 180-degree rule for a weak planet.
Yes, for small children below 12 years there is no problem; the belief that they will over-churn there is a myth. Adults' rooms should not be there, but for a PhD or research scholar the ESE is the best zone.
In a family of four, one member has an exalted planet and another a debilitated one. Whose chart decides the paintings and colours?
The house is planned from the chart of the head of the household. A member who has a separate room, such as a son sleeping in his own room, can have that room done according to his own chart.
The 5th lord is Mars but the child studies in the West. Is that wrong?
See in which direction the 5th lord sits. If it sits in the West, that is excellent; if in the East, choose the East. The East and North are best for study anyway, and if the lord sits in the South, studying in the South also works.
