Hollow rods are sold in the market; should they be filled with something before use?
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.

Can a brass pendulum be used for dowsing?
Yes. Pendulums can be metallic or non-metallic, and brass can be used because it contains copper.
How are silver and gold added to a dowsing rod?
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.
After one bone has been dug out of a plot, how can we tell whether more shalya remains there, and how much more should be dug?
More bones remained in the case discussed. Bones are traced where the dowsing rod or pendulum turns anti-clockwise, or where the swar shifts into sushumna. Remove the soil over at least a 10 x 10 ft area around the spot, 5 ft from the centre in each direction, down to the depth where the bone lay plus another 1 to 1.5 ft, and throw it away. Then purify the land.
Can a universal scanner or a similar device trace hidden elements under the ground?
The teacher challenges anyone to trace a hidden element with one. In a training, bones that generate negative energy were buried and 60 to 65 practitioners from about 15 states, using Lecher antennas, universal scanners and pendulums, could not find them. The body is the best scanner, so use the hand scanner, dowsing and swar methods instead.
Kaudi and coal also act as shalya. How are they detected, and is there a body sign as with bones?
They are found by dowsing. Any shalya produces a vibration (spandan) in the body of the person checking.
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.
