Also known ashavansamidhahawan
The biggest pooja, havan and sthapana of the 45 devtas should be done at garbh vinyas or shilanyas, while the devtas are on open ground and can receive their samagri at their own pads; the building is then raised over them.
On the open plot, at each devta's own pad
Such land can be corrected through Vastu too: special dhoop and samagri for removing bhoot-pret badha are taught later in the course.
It is a lazy, dormant land where the energy is disturbed and the fire element has fallen to zero, since sleep comes with coolness. Perform a havan with samagri, light a cow ghee akhand jyot in the South-East for eight days, and burn dhoop daily with Bhimseni kapoor on the lamp's upper plate; within eight days everyone starts waking up.
