Some devtas sit in the outer paishachik ring and some inside. Which devtas do we treat inside the house?
Your own house also has a paishachik ring. In a flat, the band along the walls on all four sides (about 1 foot in the example discussed) is its paishachik bhoomi, so mark it with the measurement taught in the previous class and treat the devtas there.

If bhoomi vibhajan is not done in a flat, is devta marking still done, given that the 32 devtas lie in the Pishach bhoomi?
Yes. Devta marking is done in a flat exactly as usual, also to judge the main door location. What does not apply is the rule of leaving the Pishach bhoomi empty: inside a flat the corners and side spaces can be used.
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.
Does everything taught today also apply to an apartment or flat, or only to a kothi?
Everything taught today applies to flats as well, except bhoomi vibhajan. In a flat it is already done: the space left around the building during construction is its Pishach bhoomi. Ati marma, zoning and directions all apply inside the flat.
Does the coconut kalash for Parjanya work when kept outside a door at E2?
Yes. In a flat seen on a recent visit, whose door is exactly at E2 (Parjanya), the resident keeps a water-filled kalash with a coconut on it outside the door and changes the water daily; the coconut has grown into a large plant, and the resident reported very good results for ten years without needing any planetary remedies. This is exactly the remedy prescribed for Parjanya.
How are the 64 pad grid and the padas of each devta worked out?
Every pad grid divides the plot into equal sections, for example 81 equal sections for the 81 pad grid; the number of padas each devta occupies is then assigned within that grid. Drawing the devtas by hand will be taught practically in the 81 pad class.
How do we mark a flat whose South-West and North-East corners are cut?
Mark it the usual way: find the centre and north, place the chakra on the centre and mark the devtas. To divide the bands, take every corner of the shape, draw lines from the centre to each, apply the ratios and join the points; a similar shape forms inside. The more irregular the shape, the more complicated the work, and software makes it easier.
