Use one whole glass mirror rather than small pieces, keep every mirror at least two feet above the floor, and never use plastic mirror film in place of a mirror.
Glass mirror (darpan), one whole piece
North wall at an entrance, and any wall of the house or temple
Every trade belongs to a planet; using that planet's colour, shape, artefacts, paintings, metals, mirrors and glass at the business multiplies its energy, while a clashing colour can shut it down.
The water element is shown by a silver or white half moon, its colour is white, its zone runs from North to North-East and its metal is silver; water bodies and mirrors represent it.

North to North-East; avoid the opposite South-East
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.
Keep heavy furniture and cupboards in the South, West or SW of the bedroom, and avoid sleeping under beams or tanks, near electronics, facing mirrors or over clutter.
Only about 55 percent of the Sun's energy reaches the earth. Of that, trees and plants capture about 95 percent, mirrors 80, pyramids 65, water 60, yantras 60 to 90, metals 45 and stones 35, while plastic and petroleum by-products capture none.

Room decoration in general; plants are chosen by planet and direction
Rules to avoid in kitchen design: no south-facing door, no doorless or open kitchen, no central platform, no mirrors or water artifacts, no toilet on any of its six sides and no well, borewell or tank above or below.
The mirror is one of the eight mangal items (ashtamangal) and is considered the best of them; it drives away negative energy and reflects energy when placed in the right direction. It represents the water element and the Moon, so it belongs on the North or East wall.
Square and rectangular mirrors are very good, but triangular and pointed-end mirrors are harmful, and mirrors cut into small pieces for scenery or glass temples (kaanch mandir) turn an auspicious item into an inauspicious one.
A mirror deepens the surface it is on: on a wall it makes the space look extended, on the floor it creates a pit. Highly reflective tiles, marble or stone must not be used in the South to West zones or the Brahmasthan.
Avoid in South, SSW, SW, WSW, West and Brahmasthan flooring
Paintings split into joined pieces, dry or cut trees, cut photos, mirrors touching the floor, swastik or Om on the floor, crying women, screaming animals, scenes of anger, crime or the Mahabharata, and God without feet should not be kept at home.
How long do the sun's rays take to reach the earth, and which materials capture the most of the planetary energy they bring?
The sun's rays take about 8 minutes 20 seconds to reach the earth, and only about 55% of their energy arrives; the other 45% is lost on the way. Of what arrives, trees and plants capture about 95%, mirrors 80%, yantras 60 to 90%, pyramids 65% (which is why fruit kept under a pyramid stays fresh), water 60% (mainly the Moon's energy), metals 45% and stones 35%. Plastic and other petroleum by-products capture none, so interiors should rely on natural materials and on indoor and outdoor plants chosen for the planet of each direction.
What should be done when Ketu is exalted in the 2nd house and the house has a North-East cut?
Rahu-Ketu belong to the South-West, and the diagonal from there is the North-East. Put a mirror at the cut, or install a kalash in the North-East and fix mirrors all around the kalash.
For a cut, should the mirror be fixed on the inside or the outside of the wall?
Fix it on the inside of the wall of the part you want to extend; seen from inside, that portion looks bigger and is extended. Fixing it on the outer side makes that part look smaller, so the outer side is used only when a part must be reduced.
A plain mirror shows about three times its size, as a 2 ft mirror shows a 6 ft person. For a 10 to 12 ft area with a 12 ft cut, use at least a 2.5 to 3 ft mirror; even a 1 ft mirror works to some extent, but the result depends on the area and the mirror quality. Use a convex mirror to enlarge a cut and a concave mirror to reduce an extension.
If the dressing room is in the SSW, can a mirror not be used there?
A dressing room has four walls, so fix the mirror on its North or East wall. If the wash basin is already in the South and its mirror must be there, fix a mirror of the same size on the North wall; the pit made in the South is matched by one opposite and the effect evens out.
Can a mirror be fitted on a wardrobe in the S, SSW, SW, WSW or West?
No. Wardrobe mirrors also belong on the North or East wall. Some say the North-West is also allowed because the mirror represents the water element and the Moon.
Our mandir is in the Brahmasthan and Lord Shiva faces West; is that a problem?
Do not worry about Lord Shankar facing West; worry only about the South, and even Hanuman ji may face South. If a deity ever faces a wrong direction, fix a mirror directly in front of the deity.
