E3 suits the main door, a library, a planning or meeting room, an office, a child's study and even a bedroom; a kitchen works only for an early breakfast, and a toilet cuts social and government support.
E4 suits an administration chamber, office, main door, drawing room, study and bedroom and gives both wealth and peace; a toilet here brings defamation, loss of wealth and disease.
East is the Sun's direction that starts creation and connects people socially, politically and religiously, so it is the zone of association and politics. Keep it open and clean; obstructing the Sun here brings trouble to the house owner.
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 earth is tilted about 23 degrees toward the NE, so this corner receives the most energy; it is the zone of clarity. Keep it low and open, use it for water, study and worship, and keep here everything you want to charge or speed up.
The Sun's light arrives about 48 minutes before sunrise in NNE and NE, carrying the most vitamin D, B12 and Ayurvedic energy, so NNE is the zone of health and immunity. It suits rooms for the elderly and the sick, medicines, water and open space; only toilets and fire are forbidden.
In NNW the influence of Kuber's North spreads sideways and attraction is strongest, so it is the zone of sex and attraction. It is the best bedroom for a newly married couple and suits display and dressing.
NW brings prana and fresh air and pushes stale air out, so cross ventilation is a must; the teacher calls it the gateway (get-away) zone. It is a natural fridge for storing grain and the Moon's place, which makes it the ideal zone for the overhead tank.
SE is pure Agneya: from 9 am to 12 noon the young Sun's fire is strong enough to cook food, so this is the ideal kitchen zone and the zone of cash flow. Water, mirrors and money storage go wrong here.
In SSE the Sun's fire moves toward its old stage and fills the place with power, confidence and energy. Everything allowed in the SE is allowed here, but no pits may be dug from this zone onward.
From about 4 to 4:30 pm the Sun reaches SW and the energy begins to cool and stabilise the mind; it strengthens relationships and skills, motivates hard work and gives stability to every work. It suits bedroom, drawing room, tijori and heavy items, subject to Rahu-Ketu checks.
The Sun sets in the West but the effect falls on WNW, which brings tears, so Vedic vastu calls it the rudan kaksh (crying room); it is the zone of depression and low mood. It is the ideal place for a septic tank and suits waste and storage uses.
From 4:30 pm until sunset the Sun's rays turn cool and soothe the brain's neurons and glial cells, so WSW is the education zone and is very good for studying children. Most activities are allowed, but no fire, toilet or main door.
A colour counts as an anti-element only when the entire room or zone is done in it; a small item of about 10 percent of the volume creates no dosh.
During study, meditation, puja, bhajan, meals and bathing, one should face North or East.
Business is ruled by Budh (Mercury), which wood represents, so office tables and furniture should be made of the best solid wood such as teak, without black or grey glass tops.
Study room colours follow the zone, but education belongs to Jupiter, so ivory, golden yellow, green (Mercury) and white suit study, as does the colour of the 5th house lord when it is well placed.
WSW, West, SW, East, North and NE are strong study zones and ESE suits research, while SE, SSE, South, WNW, NW and NNW disturb concentration.
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.
