The other four pyramids are installed on the boundary of the farm, at a maximum distance of 500m exactly north, south, east and west from the central point of resonance, i.e., the Agnihotra hut. On each point a column of mud is built, which should be at heart level of a person standing (approx. 1.2 meters), and an activated pyramid is placed on top of the column.
Small wooden boxes, if necessary with locks, can be built on top of each column, to keep the pyramids clean and safe, when they are not in use. It is important that no rain or any other material should enter the pyramids.
If manpower and materials are available Agnihotra can be performed in these pyramids also, but this is not a must.
