The earth element dominates just as in swar vigyan, where the earth tatva has the longest share, 20 of every 60 minutes. Land energy is the breath of the land; when it is obstructed, troubles begin. Classical texts such as Vishwakarma Prakash, Samarangan Sutradhar, Mayamatam and Manasara open with methods of testing the energy of the land. Within orientation the door carries the most marks, which is why it is named separately.
Cases: homes built 100 percent to vastu still collapsed financially; their land energy was minus 20, so the land was drawing the body energy of the residents. In the reverse case, a home with the kitchen in the North-East, a toilet in the West, bedrooms in the North-East, North and North-West and the tijori in the South-South-West stayed prosperous because its land energy was extremely high.
Land energy is to be tested through ashtang nimitta, swar, physical, chemical, biological, botanical and mechanical methods, nimitta gyan and the first word (pratham shabd), all taught in later classes.
