When bones remain under a plot, mercury mixed into the soil changes its chemistry and can remove up to 75 percent of their harmful effect, including the spirit trouble attached to them.
Throughout the soil of a plot where bones remain buried
If at least 6 ft of soil is filled above the place where a bone lies, even a cremation ground beneath causes no trouble, provided the 16 sanskars of the land are then performed on top.
Over the spot where a bone or a cremation ground lies
Four energised pieces of shami wood, each 11 angul long and tied with raksha sutra, buried at the four corners of a plot in an auspicious muhurta remove the vastu doshas and negativity of the land and guard it.
Four corners of the plot or land
Lime is dissolved and spread over the whole land at the bottom. The complete method is taught with the 16 sanskar of land.
Students answered griha pravesh and bhoomi poojan, which is only partly right: the greatest effect comes at the garbh vinyas or shilanyas, the day the land is taken over and the foundation is laid. Then the pishach, manushya, dev and brahma bhoomi are marked, the vastu pooja is done and every devta, 32 in the pishach bhoomi and the rest inside, is worshipped at its own place with its samagri, following the vidhi. A child cannot be born without a seed in the womb, and food works only through the mouth, not the ear or nose, so the biggest pooja, havan and sthapana belong to that day; building over the devtas afterwards is like tethering a cow first and then building its shed. Done later, remedies bring back only about 35% of that role, though even 5% is a lot.
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.
Removing the bone is not enough; the land needs its rites, just as a house is purified after a death. Do a vastu registry with five coconuts (four corners and the bone spot), remove the affected soil, do agni sanskar with mango wood, ghee and camphor in 16 places and float the ash in flowing water, purify with water and mantra, sprinkle gomutra and plaster with cow dung, put lime and sulphur in the pit, keep a lamp burning there for 24 hours, and mix a little mercury into the soil and the four corners. If the shilanyas had already been done, it is broken and must be redone after purification.
