Also known asagarbattiincensedhoop batti
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
Pendulums are metallic (copper, silver, steel, brass) or non-metallic (quartz and its variety amethyst); a genuine, heavy pendulum is cleaned in salt water, purified with fragrant dhoop and given the intention to work with you before any use.
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.
