The full purification done where a bone has been dug out, the land's equivalent of the rites after a death: vastu registry with five coconuts, removal of the affected soil, agni sanskar with mango wood, water, gomutra and cow-dung purification, lime and sulphur, a 24-hour lamp and mercury.
The spot where the bone was found, the surrounding soil, and the four corners of the plot
Blowing a conch sends the energy of the body's 72,000 nadis through the calcium phosphate particles of the shankh into the air, driving negativity out of the whole house or factory and removing bhoot-pret badha.
Whole home, factory or plot
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.
