Bio- geometry for directional reversers used for south facing, NE/SW toilet rectification and big beam corrections.Working people sitting facing south permanently need a direction reversal.
Use a metal or wooden swastika and paste a metal reflector on top of it in the center and then install it in front of the wall which needs the reversal.
It can be either one in the center of the
opposite wall or 2 in each corner or sometimes 3 (two in the corners and one in the center).
Thus, if you are facing south then install it on
the wall in front of you.
This would virtually bring north in front of you.
It is used for correcting beams above working or sleeping areas.Also, for correcting Brahmasthan columns, used at the base and top of all corners.
