Should the gomti chakra swastik plate be fixed inside the wall, or can it hang outside where people see it?
It need not be hidden. The swastik is the most energetic symbol, and you already hang curtains and many other things that people see. Hang it or stick it as the space allows; if you keep worrying about what people will say, it will not give results.

Can yellow mustard and gomti chakra be put at a South-West main boundary gate?
Yes, it will benefit. These two items are not limited to any direction and can be used anywhere. Put the yellow mustard in properly dug pits, because if it meets moisture and sprouts it does no good. The specific South-West gate remedy is taught separately.
Houses abroad have back doors opening into the garden that do not lead to the road; do these bad entries need treatment?
Such a door is not counted as an entry; it is a prishth bhang dwar (rear door) that lets the negative energy of the house out. Energy enters with you through the door you come in by. No treatment is needed; if it bothers you, draw the energy-blocking swastik. Symbol vastu especially suits countries outside India, where demolition is not possible.
If doors are already open on wrong padas, how are they treated in interior vastu?
Vedic vastu says the defects of a wrongly placed door can be removed through the decoration of the door itself: auspicious symbols, yantras, paintings and artworks made on the door, door power at the threshold, and a bandhanwar (toran) hung on it. This class therefore treats wrong doors with symbols, torans, bandhanwars and colours rather than structural changes.
In door power, along with quartz crystals, can gomti chakra, yellow mustard and white mustard be added?
Yes, and more than ten grains can be used. If the pit is dug about 10 to 11 inches deep, add yellow mustard. In the dehleez, white mustard must always be put, in good quantity.
My main door is in the South; how should it be treated?
In interior vastu a wrong door is treated only with symbols and similar items, since the full door treatment alone would take about five classes. For South door defects the class gives bandhanwars of stone or gems, a toran of copper and wood, and a red triangular swastik bandhanwar hung on a Saturday or Tuesday. In the South only S4 is a good pada, and it suits those with Kark, Makar or Kanya rashi, mulank 9, or an exalted or own-sign Mars.
The house door falls on Parjanya (E2) and the family has more girls; why, and what can be done?
A door at Parjanya makes the house female dominated: females are more in number, more female calves are born and the first child is often a daughter, though this also depends on the fifth house of the horoscope. The remedy is to make the Om and swastik symbol taught for Shikhi at that door.
