Dowsing with a pendulum can be very helpful. Everything from picking beauty products (people have varying sensitivities and preferences), and picking out foods, to knowing you exact weight minus water weight of course, can be answered with the pendulum. I love it. I first got introduced by Sonia Choquesttes book Develop your intuition, workbook. It has a section for this. Here are your divination basics: You don't need to buy one although if you really like it, you may want one. Use a necklace, ring on string or ring on chain. I have heard rings on fishing wire work too. Calm yourself down, relax take some breaths. Say a prayer like
"I ask my guides and God to now clear my chakras of any fear. I ask to be filled with truth, love and hope. I ask for the truth so I can know how best to act and handle certain situations. I fill my room with light (pick a color, white, purple and gold work well). Then hold the pendulum from your dominant hand straight down. Ask your guides to show you your yes, no and maybe with this pendulum. My yes is up and down. My no is side to side movements. My maybe is circle. My friend had a completely different set of answers and movements for hers. When using her pendulum, I notice d it followed her system!! Talk about an energy imprint on a an object. So ask beforehand. Its best to use one item. If using jewelry, wear for at least 12 hours and clear it of past energy. You want a sensitive accurate instrument so you can really make good judgments. Once comfortable and when you find it reliable, you will rely on it appropriately. Good luck. Love to hear your stories.
