To dowse is to search, with the assistance of simple hand held tools or instruments, for what is hidden from view or knowledge. It can be used to to locate water, minerals, artifacts, or other objects. Dowsing can be carried out at a distance for something missing as close as in the next room or the next continent. For example, holding a pendulum over a map until it swings in a manner to indicate the area where the object is located. Dowsing is frequently used by health practitioners to help pinpoint causative factors and suitable remedies. This can be done even if the practitioner is at a distance from the patient, by employing a proxy of the person, or recent photograph for example, on which to focus their attention. Dowsing is also a great tool to use to see if supplements, products, or foods are biocompatible with your system.
