Also known asvastu shantihavanvastu devta vidhan
During aahuti with the Bhoomi Jagran Mantra, the flame takes the shape of whatever negative object lies in the land; photographing the flame and studying it shows what is buried there or what has been done to the land.
On the land being tested
The custom of boiling milk in a new home is a nimitta test: milk that boils over silently is auspicious, while crackling or popping sounds show that some ritual remained incomplete or a defect remains in the construction.
Kitchen fire of the new home
Aahuti (oblations) are offered with fragrant dhoop to each of the 45 Vastu Devtas on the land; the devta at whose aahuti a sneeze, itching, crackling, harsh words, a frightening sound or crying is noticed marks the zone where the land holds a defect.
On the land, over the zones of the 45 Vastu Devtas
An earthen kalash full of water, topped with a coconut and five mango leaves, is set on a heap of wheat in the North-East of a built home; the colour, shine and growth of the javare that sprout from the wheat show the energy of the home.
Ishaan (North-East) corner of the home
When bhog samagri is offered at a devta pad holding negativity, the defect tries to come out: tiles, plaster or ground may crack, or itching or heat appears in the body part linked to that devta.
All devta pads
Yes, advise removing it: the North is Kuber's place, and keeping filth at the place of wealth is like putting dirt in the mouth, so wealth cannot grow. After any demolition do a Vastu pooja; even a short one is enough, offering 45 small pieces of gud to the 45 devtas or invoking the nine lords with Bho Indra Vastu Dev Vastu Shanti Kuru Kuru and so on for each direction, with Brahma at the centre.
No. Keep the samagri simple and do the pooja from the heart; any pooja is an offering of feelings, and what matters is the bhav offered, not whether paan or gud could be offered.
The water mantra chanted while pouring water into the pit is not found in Jinvani; it was to be shared with the class group (exact words: refer to the class recording), and the Gayatri Mantra can be used instead. The Bhoomi Jagran Mantra used for aahuti on the land is found in the book Pratishtha Parag, a text on pratishtha (consecration).
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.
On the ground. That is why they should be established at the shilanyas itself, and their bhog samagri is offered on the ground at each devta's own place.
No, goods lying there are not arpan or samarpan. A guest never picks sweets off the dining table himself; they are served on his plate and he is invited to start. In the same way, serve the devta its bhog in a leaf dona or on a paan leaf, which the devtas love, and request it to accept the offering and increase the energy of the place. If the pooja was not done during construction, offer it at griha pravesh: any dish made in desi cow ghee, such as gujiya.
In a full vastu poojan all 45 devtas are worshipped and offered together. When one particular devta has to be activated, offer its bhog samagri or do its jaap in its own time slot for the maximum result. An offering at another time is not useless, but just as food eaten at the fixed time of hunger satisfies more, the result differs.
In a vastu pooja all 45 devtas are activated together in one sitting. A single devta can also be activated on its own with its samagri at its own time.
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.
Someone who represents Brahmin qualities by conduct, not by birth: a vegetarian of good character with a pure mind. A person who eats non-veg, drinks or does wrong deeds turns the pooja into a mere show. Wear the janeu, purify yourself and wear clean or new clothes.
There are 45 devtas, but 4 more devtas stand on all four sides to protect them, so basically there are 49. Bhog samagri is offered to these 4 guardians as well, after the 45.
