Hold the Pendulum by the chain so it hangs down & ask a question such as “do I live in ***** (your town)?” & notice if it spins to the left, right or backwards & forwards.
Then ask it which way is yes, & it should swing the same way.
The next question is ”which way is no?” & it will do something different – make sure you remember which way is which..
The way the Pendulum swings for No is usually the same if it’s confirming the presence of negative energy.
Holding onto your Pendulum walk slowly around the place you want to clear; it should swing with some strength when it comes across negative energy. When it starts to swing step slowly backwards until it stops, this will help you feel exactly where the negative energy starts & finishes. Now you know where to start clearing the energy out! Palo Santo or Sage is really great for this, use it in all corners of the rooms as well as the specific areas you’ve found. Then open all the windows & doors & give the house a good airing, letting the clean energy flow through. If you’re a Reiki practitioner use your Reiki power symbols on all the windows & doors & the centre of the rooms & of course give thanks when you’ve finished..
