Some notes about the Hartmann grid (from my experience):
– The position of Hartmann lines is usually determined with L-rods, Y-rod or Pendulum. These devices play the role of indicators and the real detection is done by hand’s motion centers from the parietal lobes of the human brain (the left center for the right hand and the right center for the left hand). This fact can be easily highligted with L-rods by a lateral displacement of the body(or of the head) perpendicular crossing the Hartmann lines.
– The same experiment can show that Hartmann “lines” have the width much smaller than the one mentioned in the literature (16-21cm). Position your body so as a line Hartmann cross the space between the motion centers of the hands and the L-rods remain parallel. It is possible that the width of the Hartmann lines to be close or egal to zero(?!.)
– All the beings (creatures) avoid sleeping on the lines of Hartmann grid. People, in the absence of external constraints (housing, family, architectural, financial, aesthetic, educational,etc.) unconsciously avoid sleep in positions crossed by Hartmannn lines. Few houses are built on the N-S direction in order to optimize the use of the nonpathogenic areas from Hartmann grid. Generally, single beds can be arranged so as not to be crossed by these lines, but at least one of the co-occupants of the double-beds is placed in the risk area. Fortunatelly, we found that the single-occupants of the double-beds reflexively choose the less nonpathogenic areas of the beds for sleep.
