After a birth or death in the family (sutak or patak) the Vastu devtas are affected too, so the whole house is purified: clothes are washed, raw clay vessels are thrown away, a dhoop kund is carried through the house and offerings are made to the Vastu devtas.
Whole house
After demolition or the removal of a defect, a short Vastu pooja is done even when a full one is not possible: offer 45 small pieces of gud to the 45 devtas, or at least invoke the nine lords of the directions and the centre with the words Bho [name] Vastu Dev Vastu Shanti Kuru Kuru.
Each direction of the house, and the centre for Brahma
If the foundation stone (shilanyas) has been laid in the wrong direction, the earlier shilanyas is formally dissolved and a fresh one is performed in a new auspicious muhurta.
After zoning, mark the 32 outer padas of 11.25 degrees each: Soma (N5) is centred on exact North, extending 5.625 degrees on each side, and the remaining padas follow every 11.25 degrees.
For 32 zoning each pad is 11.25 degrees, with N5 centred on the exact north (0 degrees). Start 5.62 degrees on either side of north and mark every 11.25 degrees, or mark the black lines of the zoning chakra.

On a real plot of any shape, the ati marma are marked by finding where the twelve devtas of the six ati marma lines meet the plot boundary and joining those points. With the zoning chakra this takes one to two minutes and needs no computer.
Whole plot or flat, using its boundary
After bhoomi vibhajan the 45 Vastu devtas are marked by angle: the 32 outer devtas at 11.25 degrees each in the Pishach bhoomi, four main inner devtas at 54 degrees and eight others at 18 degrees in the combined Manushya and Dev band, and Brahma in the centre.
Pishach bhoomi for the 32 outer devtas, the combined Manushya and Dev band for the 12 inner devtas, the centre for Brahma
In the 81 pad (9 x 9) Vastu mandala the ati marma are found by drawing six lines between pairs of outer devtas: the two corner diagonals and two lines parallel to each of them. Their nine crossing points are the ati marma.
Whole plot; the crossings fall mostly in and around the Brahmasthan
The logic used on paper works the same in AutoCAD, Corel or any drawing software: scale the house outline by the bhoomi ratios, divide by angles, and keep a ready template of the chakra and devta lines to overlay on every new map.
Digital plan of the house, plot or flat
A quick manual method to divide any plan into the concentric bhoomis of the 81-pada grid by multiplying the centre-to-corner distance by 0.33, 0.55 and 0.77.
Whole plot or building plan of any shape
Bhog must be served to each devta at its own pad, in a dona made of leaves or on a paan leaf, with a request to accept it, just as food is served to a guest. Items merely lying in the house are not an offering.
At each devta's own pad
After the bhoomi rings are drawn, the outer ring is cut into 32 pads of 11.25 degrees each, starting with Som devta centred on North, and the middle ring into 12 inner pads with an 18-54-18 degree split for each direction.

A small havan at the Shikhi pad with a teaspoon of desi cow ghee mixed with a spoon of shali dhan, offered as nine aahutis with the devta's mantra, multiplies the energy of Shikhi.
Shikhi pad, E1
In earlier times, when someone at home fell ill, people put ghee and a little rice on a cow dung cake (kanda); this was a method of activating the vastu devtas.
Bhog samagri is offered devta by devta, always starting with Indra (E4) and moving through Agni, Yama, Nairiti, Varun, Vayu, Kuber and Ishan through all 45, then to the 4 guardian devtas who protect them on the four sides.
Each marked devta pad on the house plan
Place a protractor on the house plan aligned to North, adjusting for any tilt, and mark the 4 directions, the 4 sub-directions at 45 degrees and 8 further sub-directions at 22.5 degrees. For a house use the 81-pad layout, in which the 32 outer devtas each cover 11.25 degrees and N5, E5, S5 and W5 fall exactly on the cardinal points.
House plan, from the centre of the house
Do not think of it as a lamp burning for 24 hours in the Agneya (South-East). Use a small diya and place it in the Ishaan (North-East), because the devtas seated in the Ishaan, such as Shikhi, help a great deal.
Fix a fresh auspicious muhurta for shilanyas, dissolve (khandit) the earlier one, and perform it again in the new muhurta. It is dissolved the way an installed kalash is removed: by addressing the devtas who supported the earlier shilanyas with a request about it.
A pad is one of the equal sections into which a plot is divided. For 81 pad vastu a house, for example 90 by 90 ft, is divided into 9 by 9 equal sections and each section is one pad; the larger grids, such as the 1000 pad grid, divide the plot into many more equal sections. Some areas such as the Brahmasthan cover several padas together even if the drawing does not show their inner divisions.
Exact North falls on Soma (N5), with Bhallat at N4. The North zone is made of half of Bhallat (5.625 degrees), the full Soma (11.25 degrees) and half of Bhujang (5.625 degrees); North falling between Bhallat and Soma belongs to the 64 pad grid. The North-East zone is half of Diti (5.625 degrees), the full Shikhi (11.25 degrees) and half of Parjanya (5.625 degrees).
No. In 81 pad vastu exact East falls on E5 (Surya); East between E4 and E5 belongs to the 64 pad grid, so correct it. The reference is in Vishwakarma Prakash, with the page number given in the previous class; the Hindi translation from Sanskrit by Krishna Kumar Jugnu of Udaipur and the edition of Maharshi Abhay Katyayan give the same.
The colour on the chakra is the colour of the devta of that zone, not of the element; the North devtas are shown in red, for example, which is not a colour to paint there. The air element has both green and blue as its colours.
If the N1 pad is available, place them in N1.
Every pad grid divides the plot into equal sections, for example 81 equal sections for the 81 pad grid; the number of padas each devta occupies is then assigned within that grid. Drawing the devtas by hand will be taught practically in the 81 pad class.
Colours are taught in interior vastu; do not get confused now and focus on what is being taught.
There is no criterion for finding the centre; the centre is always the centre. The proportion matters for the plot itself: up to 1:1.5 is good (30 x 45 feet is ideal), up to 1:2 (30 x 60) is neither good nor bad, and longer than that is not good, with more loss the longer it gets. In such long plots many devtas fall outside or get cut, and they need treatment.
No special software is needed. Draw the chakra and devta lines once in AutoCAD as short reference lines; for every new map just align them and join the lines, which takes about a minute.
Yes. Devta marking is done in a flat exactly as usual, also to judge the main door location. What does not apply is the rule of leaving the Pishach bhoomi empty: inside a flat the corners and side spaces can be used.
