Copper (Tamba)

Yes. Pendulums can be metallic or non-metallic, and brass can be used because it contains copper.

There is no need to fill anything; do not use a hollow rod at all. Solid copper rods, 8 or 10 mm thick, are sold wherever copper is sold; simply bend one into an L.

On a Guru Pushya or Ravi Pushya yoga, have a goldsmith mix them into the copper and make the rod. If that cannot be done, take ready-made rods and have silver and gold fixed at their solid point.

Either remove the toilet, which is rarely practical, or keep the two flats separate through kilan: four copper nails at the corners of one flat and four at the corners of the other. At griha pravesh a raksha sutra is tied around the house and nails are fixed at the four corners so that the current moves along them, and kilan divides the current the same way. Even on the third floor, simply drill and fix 1.5-inch copper nails.

In Vedic vastu each direction represents a planet: East is the Sun (gold and copper), South-East is Venus (white metal), South is Mars (copper), South-West is Rahu-Ketu (panchdhatu), West is Saturn (iron), North-West is the Moon (silver), North is Mercury (kansa and brass) and North-East is Jupiter (gold and brass). The planets cannot be held in a fist, but their energy can be deposited in the home: the material representing a direction's planet captures that planet's energy there, multiplies it, raises the power of the place and nullifies negative energy.

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.
