Vastu results depend equally on four factors: dravya (the money used), kshetra (the land), kaal (the muhurta) and bhav (the feelings of the builders and residents). A perfectly planned house still fails if any one of them is wrong.
The janma rashi (Moon sign) runs the whole life and is used for stable works such as house construction muhurta and marriage, while the rashi of the name in use can be used for business records. Naming a child by the janma rashi keeps the person's element unchanged.
Because work begun with the sun's energy goes well, and after sunset creation is considered asleep. So griha arambh, griha pravesh, factory openings and other mangalik events are held in daytime.
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.
Dussehra and Diwali are the best muhurtas for kilan.
Each outer devta has a sadhana period of 45 minutes, so the 32 outer devtas complete the 24 hours (32 x 45 minutes) and come back to the same point. Shikhi's period runs up to 3:00 am and Parjanya's from 3:00 to 3:45 am. Havan and offerings made in a devta's own period wake and activate it quickly.
Every devta has its own month; Shikhi and Parjanya stay awake in Shravan (Sawan). The coconut kalash can still be placed at Parjanya after Shravan has passed; once Parjanya is awake it fulfils the wishes of the residents, so that in such a house whoever enters and voices a wish sees it fulfilled.
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.
It is a 45-minute period. The count starts with Shikhi devta from 3:00 to 3:45 am, and each next devta takes the next 45 minutes.
There are uttarayan and dakshinayan suns. When the Sun is uttarayan its composition is more energetic, so all auspicious ceremonies are done then; the dakshinayan Sun's composition is not as good. The zone layout does not become wrong; the Sun's composition at each angle of inclination explains which energy is needed for which work.
The janma rashi runs the whole life, so all stable works such as the muhurta for building a house and marriage are done by it. If the name is not from the janma rashi, its rashi gives a different element, which can be used in business, because bank, GST and tax records carry that name.
When the main door is installed in a muhurta, its four-piece frame (chaukhat) is set up and the base piece of wood is the dehleez (threshold). Door power means installing that dehleez in a muhurta combined with the right swar, with the prescribed samagri, such as silver and pancha ratna, placed in the ground beneath it. Done this way, even a door in a wrong place has about 50 percent of its defect removed. The full door treatment is part of the complete course.
Take a shubh muhurta for dehleez installation (the teacher posts dehleez muhurtas every month) and have a dehleez made. It should still be of wood; make it of stone if you want to become firm and of wood for a softer nature, choosing the type of wood by the qualities you want.
Select a muhurta if possible. Otherwise make swastiks for shanti and paushtik (peaceful, nourishing) work in the Chandra swar and for ugra (forceful) work in the Surya swar. Any remedy done in the wrong swar gives no result.
