Dowsing, in general terms, is the art of finding hidden things. Usually, this is accomplished with the aid of a dowsing stick, rods or a pendulum.
The dowsing rod is a simple instrument. Taking the short end of the rod(s), rest it over your first three fingers, sit the pointed end of the rod on your little finger and use the thumb to stabilize the rod at the back. Curl your fingers around the rod and it should now point out with the long end (the right angle to the piece in your hand) pointing away from you. This is the most effective way of holding a dowsing rod of this type.
Holding and working with your metal divining rods In order to search for anything using a rod, you must clear your mind and then focus very clearly on whatever it is that you are looking for. It helps to say the name of the object over and over as well as visualizing it in your mind. For example, if you were looking for water, you would get a picture in your head of clear, fresh water and then as you were searching for it, you would say over and over "Water, Water, Water". This helps to prevent other thoughts wandering in and it keeps the mind focused on what you are looking for.
Rod divining involves a great deal of walking, as the rod will only spin when you are over what it is you are searching after guiding you to the site. Hence it can be a tiring method of divining. Still, it is one of the most accurate methods of all. Particularly if you own the rod you are using. It is as if you develop communion with the rod. In working with the rod you are attuning to its energies and it becomes at one with you. Once you get a clear picture of what you are looking for walk slowly and gently in the direction the rods are pointing, this is the direction to what you are looking for. Walk slowly and deliberately and allow the rods to move freely. As you walk the rods will move and point to another direction, carefully turn your body and follow in this direction. Your rods are now guiding you to what you are looking for. When they reach the area of the desired object, the rods will cross over each other in front of your body, indicating they have found what you were searching for. When you first begin, it may be fun to look for easy things i.e., - take me to a particular animal or family member in the house.
