Also known aswindowventilator
Where a problem persists, create a window at the point where the sun's gold-bearing rays fall at sunrise; if no opening can be made, draw a symbol such as a swastik there so that it captures the energy and fills the place with it.
Where the air element is disturbed, for example in a rented flat that causes gastric trouble, use green colour in the North-West, put up a flag (dhwaj) there, preferably a five-element flag, and open the North-West with a window.
This is taught while preparing maps: for summer, the rainy season and winter, the particular angle at which the rays strike and their composition are worked out, so that openings and walls can be planned for the maximum benefit without demolition.
Every house used to have ventilators at the top of the walls, which balanced the air element. They have been brought down into the windows, and since the ventilator location changed even a ten-year-old child argues back. Keep the air element balanced with proper doors, windows, top ventilation and cross-ventilation.
Use green colour and a flag-like pattern: put up a flag (dhwaj) in the North-West and, if possible, open the North-West with a window; this brings at least some balance. Swar vigyan can do still more without expense or demolition.
Only about 25% of the results, because the subtle currents do not come in; only the surface cosmic currents reach.
No. The chaukhat is the four-piece frame, and a window or glass above it is not counted in the door aay, because fixed glass stays closed; glass that opens and closes would be counted. Fixed glass above a door is itself used as a remedy.
Yes. The North results then start coming, though not fully; you get as much as is open. Through a window only air comes in, whereas people come in through the door.
No problem. As taught in interior vastu, make one symbolically, and if that is not possible, make a figure (picture) of it.
Outward. The door brings energy into the house, while the window is there to throw out the negativity created inside, so its shutters should open outward.
An office needs ventilation, so a basement does not suit proper work. Only businesses of an adharmic nature, such as some salons and facial parlours, run well in basements; they do not need pure energy like the Sun's.
A door is placed by pada, but a window does not work on the surface current: currents are dense near the ground and lighter higher up, so positive energy stays higher, which makes ventilation a must. Windows and ventilators bring in clean air and push the negativity of the house out, so they should open outward, while the main door opens inward; sliding windows are acceptable. Keep windows in even numbers, two-shuttered if possible, in one row at one level, with a window beside the main door; open all windows in the morning and keep the left (Chandra swar) window open during the day.
In the North anywhere from N1 to N5; from N8 across the East up to E7, but not at E8; in the South on S3, S4 and S5; and in the West on W3, W4 and W5. These are the green-marked padas of the window chart.
With UPVC systems whole sections can open, so at least open the part that has an opening system, wherever possible. Following the allowed span, the East from E1 to E7 can be opened fully, at least five padas of the North, three padas of the South and three or four padas of the West.
