Energy Shifter is used to virtually shift wrongly placed rooms to their rightful zone as per Vastu. One shifter is to shift energy from the negative zone and another to the place where you want the energy to be redirected.
For example, if your toilet is in a negative direction, you can use two shifters to redirect the negative energy to the right positive direction, according to Vastu. This will eliminate the negative effects of the toilet.
