Casting Directions for ‘A Simple Dowsing Pendulum’
Now take your item you made or chose. . .and join it with the string, the string has to be able to stand from the top not, tie the knot tight so that it dosnt slide. Find no place and its yes. You can also hold it and control it, or set from the windowsill in sunlight or moonlight. Put to wash it some things shouldnt be placed in saltwater so if thats the case just put in salt or dirt. I advise you place it on leaves, dip it in water for well water and in dirt or sand for earth or enchant it with the elements, example put it through incense for air. . .like when you make runes. It you have and item that shouldnt be in water wash it off and get a bit of water or put it over steam. I hope this was helpful and enjoy your pendulum.
Now to use a pendulum once you create it you simply hold it correctly by putting the string between your index finger and your thumb then relax your hand downwards or look at a picture of how its done(I have one in my album, my record is public) now either think the questions on your head or say them aloud but before questions request it whats your yes place mine personally spins clockwise or counter clockwise yes and back and forth or side to side for no, then you have to ask whats your no position. For beginners dont worry about positions yet. Now after you ask a question ask is this true and give a little time to it. I start off with are my eyes brown that is yes then are my eyes green that is no. You dont know the awnser to correctly now if it is given a nudge by your pendulum dosnt move.
