Is a rooftop water storage tank also counted as the water element?
Yes. Water stored anywhere, including on the roof, represents the water element. But if the tank is built in a square shape, it moves to the earth element, because the square is the earth element's shape, and it becomes an earth combination.

Can the dining table be round?
Yes, a round table works if it is placed in a water-element zone. Furniture shapes for each direction are covered in the next class.
Can wardrobe doors go from floor to ceiling?
No. Doors taken up to the ceiling start touching the space element, which is not good.
Drainage is listed under the water element. Is a drain line in the water zone negative?
Underground water movement 1.5 to 2.5 feet below the surface is not treated as directional, just as groundwater flows in every direction under the land; it becomes a dosh only when water is drawn up. So the drainage pattern itself is not a dosh. But a drain inspection chamber built at a wrong place and left open causes trouble, and dirty water flowing anti-clockwise has a considerable negative effect.
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.
Is interior done only for beauty and maximum use of space?
No. Interior is done to use the maximum energy of the universe, balance the five elements, control particular emotions and achieve a particular goal. Every painting, artefact, idol, colour and orientation changes the mind through images (chitra se chitt), so the interior itself can balance the five elements, the nine planets and the three forces of a home, temple or factory.
Only one friend and one enemy were given for each element. Is that the complete picture?
No. The element relationships are taught in much more detail in interior vastu, including the cases where two elements come together in one place.
