The Q Circuit is an amazing advancement in the field of Vastu. For strong, 4-polarity grounding of the electrical circuitry in the home just plug a Q Circuit into an outlet near the center of your home (or where the majority of your devices are). Small houses typically need only one.
Larger houses or highly EMF stress properties may need two. For those of you that use muscle testing or dowsing, test the field at all three levels before and after plugging this in and watch what happens! You'll be amazed at how well it grounds the wall circuitry throughout your entire house.
