Radiesthesia is a term used to describe the practice of detecting energy fields and radiations emitted by people, places, and objects. Some practitioners believe that this ability can be used to diagnose health issues or locate lost items. It combines elements of dowsing and metaphysical healing, often involving the use of tools like pendulums or rods.
The word 'radiesthesia' is derived from two components: 'radio-' from Latin, meaning "ray" or "radiation," and 'aesthesia' from Greek 'aisthesis,' meaning "sensation" or "perception." Thus, it can be understood as the perception of radiation or energy.
