Dowsing is not just for finding water. It can be used for first aid, to cure or alleviate chronic sickness, to make things in your life flow harmoniously, to "ghost bust," to get rid of noxious energies that screw up your life, to determine which foods are still edible, the proper dose of vitamins and which brands will actually work for you, decrease or get rid of your medicine's side effects.
I've pendulum dowsed professionally for 37 years and never encountered one person who can not learn to do it, although I admit some have more of a knack for it than others.
If you are interested it is not a free ride: I won't charge anything to hold your hand as you learn and gain confidence, but there are things you have to get. First is a pendulum! They can be found cheaply on eBay. It makes no matter what the pendulum is as long as it is pleasing to you. The second is the free very beginner text, "Letter to Robin, " by the late Walt Woods. You can get that here: http://www.lettertorobin.org/Home.html where it is available in several different languages (I can teach you in either English or Spanish but no other languages ;-) You also need to buy two other things from Raymon Grace at http://www.raymongrace.us/products.html They are: the DVD, "Explaining the Dowsing Chart," and "Techniques that Work for Me." These will blow your mind as to what you can apply dowsing and up the quality of your life severalfold. All of his other DVDs are totally well worth the price if you want to buy them as well (personally I'd skip the Being with Bowls CDs and fork out for all the rest: this is a truly magical skill for preparing accordingly.) If you just want one-stop shopping Raymon sells three different kinds of pendulums: stone, metal, and for us survivalists, bullet. So you can snag a bullet pendulum while you are getting the DVD and book and have everything you need arrive in one package. We can work together here or by private email depending on your preference. This is my service to the Turd community even though I realize that a lot of members will dis it. That's OK. We all steamboat when comes our steamboat time, but dowsing can be applied to ANYTHING under the sun including finding out if the metals markets tomorrow will trade up or down tomorrow, etc. etc. etc. so it's well worth a small investment of money and your time to learn.
