Is there any AutoCAD software for marking the marma points?
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.

If furniture made by carpenters is placed on a devta's pad, does it affect the devta?
All 45 devta places cannot be left empty, or there would be nowhere to live or keep things in a house or flat. The Vedic texts say to protect the ashtamansh (one-eighth part of the pad); wooden items kept on any devta's place, even on a marma, are not counted as a dosh, because wood does not sink in water but floats. Besides, the devta's place lies beneath us, and the devta is basically a particular energy.
A client's location shows coordinates. What do I do with them?
Copy them and paste them into the Google Earth search bar, which takes you to the place. Then draw a straight line along a wall of the building to get the degree. A degree taken from the centre is wrong; the centre only tells you which direction a room is in.
A gallery or balcony outside a room was open at first and later covered; should it be included in the map?
Include it in both cases, covered or not. You go there and move around in it, so it counts as part of the house.
A regular plot has small strips of land left open at the side and the front. Do we leave them out or zone the complete plot?
Zone the complete plot. Almost the whole plot is in use and even the small strips are being used, so the full plot is taken for zoning and for the degree.
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.
