Also known asflagdhwajajhanda
When the neighbouring house in the East is taller than yours, you lose the energy of the sun. Either add a storey or raise a metal flag of brass in the South-West of your roof, higher than the neighbour's building, so that your building starts receiving cosmic energy.
Metal flag (dhwaj) made of brass
South-West of your own roof
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.
Flag (dhwaj), preferably a five-element (panch tatva) flag
North-West zone
You are losing, because the East (the sun) gives all the energy. Either build a second storey or put up a flag: a metal flag of brass in the South-West of your roof, higher than their building, so that your building starts receiving cosmic energy.
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.
A five-element (panch tatva) flag.
Balance it by fixing a dhwaj (flag) in the South-West.
