Example: on a 100 x 100 plot, a 35 x 35 house is built with a right-angled plinth beam and columns. The geopathic current starts moving in that right-angled shape, so the shape is regular even if balconies stick out above. In the Vastu Purush mandal, balconies are like the hair on a head; long hair spread out does not change the shape or height of the body.
Barfi analogy: in a tray of set barfi (kalakand), the piece cut out with a knife carries its own current, and even its own temperature, along its edges. The land is a big barfi, and the bhukhand cut from it, defined by the foundation, is the shape.
Many consultants have wrongly told owners that their ishaan is cut and made them alter their houses; the teacher finds about 90 percent of such zoning wrong.
