Can a Vastu Devta already be active without any remedy?
Yes. Sometimes the devtas are active on their own because of one's punya and good karma of past lives; they are like old friends who wake up again when one comes to live on that land. They also become active when one moves in with the permission of the people already living there. The activation tests show whether they are active.

If many things are already kept at a devta's place, does that count as an offering?
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.
When do the Vastu Devtas have the greatest effect, and when should they be established?
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.
About 11 or 12 of the 45 devtas are asuras. Whose energy should be increased and whose kept low to stay balanced?
This was to be explained in detail later, as there is a big confusion about it. Asura devtas are also needed: the day there are no asuras in your house, your work will not run, so the aim is balance, not removing them.
After placing sweets and later chanting the mantra 27 times at a devta place, I felt strong heat in my body. Why?
It shows a defect or imbalance at that pad. When an offering reaches a defective place the defect tries to come out, as when granite tiles at one devta pad cracked during a group havan, and the body reacts. The uneasiness is a signal: the pad must be purified and activated with the method being taught (havan samagri, bhog samagri, mantra or the samagri to hang), so wait for the full method before trying again.
Are the 32 outer devtas drawn in the Manushya bhoomi or in the Pishach bhoomi?
In the Pishach bhoomi, the outermost band. The 32 outer devta lines are drawn only within the Pishach bhoomi, while the 12 inner devtas sit in the combined Manushya and Dev band and Brahma in the centre.
Are the symbols used in these treatments, such as the swastik, Vedic or newly made?
The symbols are taken from the Vedic tradition, such as the swastik, but they are designed with an added element that generates and spreads their energy, and the material they are engraved on matters. Each piece was to be shown physically in class.
