Also known asland worshipbhumi pujan
Items placed under the ground at bhoomi poojan or shilanyas, such as the naag-nagin pair, the foundation stone (shila) and the kalash, and treatment items such as pyramids or silver and gold nandavart, give results only when set at water level (zero degree).
Under the ground at the shilanyas or treatment point
At the shilanyas or bhoomi poojan of any house or factory the first tilak goes to the mason (shilpi), contractor or Vastu consultant, not the pandit, and they are given the best clothes and a shriphal (coconut). Their goodwill enters the building, while a craftsman's tears of hurt in the mortar act like a buried bone (shalya dosh).
Vastu pooja is the prana pratishtha of a house: just as an idol is not worshipped until its prana pratishtha, a house is established only through Vastu pooja. It is due at fixed stages of construction and again whenever the house is disturbed.
Because the feelings (bhav) of the builder enter the building. Honouring the mason, contractor or Vastu consultant with tilak, good clothes and a coconut makes him work with joy, while a hurt craftsman's tears in the mortar bring repeated sorrow to the house.
No. A farmer who sows a seed does not end his bond with it there: he protects, waters and nurtures it until it flowers, fruits and grows into a shady tree, even a kalpavriksha (wish-fulfilling tree). In the same way, Indian architecture holds that a structure of stone and lime is not lifeless; prana settles into the building and its soil and controls the feelings of the people who live there, so the devtas established in the land must keep being nurtured.
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.
No. Do it at bhoomi poojan or shilanyas, when the first slab is laid, when the main door frame is installed and on griha pravesh; the start of construction and griha pravesh are essential. Also do it after a renovation in which walls are broken, for a marriage, the start of a job or business and the birth of a child, and once a year on a swayam siddh muhurta such as Akha Teej or Gudi Padwa for a year of happiness and peace.
