Energy and Power
The term energy has been widely adopted by writers and practitioners of various forms of spirituality and alternative medicine to refer to a variety of ideas, often (though not always) conceived as "fields" surrounding the earth or any living thing, supposed to be directly perceptible and accessible to the human mind as "auras", "rays", "fields" or "vibrations".There is no scientific evidence for many such fields, in any sense in which energy is currently defined in science. In many cases "energy" is conceived of as a universal life force: to this extent "spiritual energy" theories resemble vitalism and may even invoke the Luminiferous Ether of Victorian physics. Additionally, or alternatively, such notions are often aligned with or derived from conceptions found in other cultures, such as the Chinese idea of the Prana of the Upanishads Many such ideas arise from the primitive idea of life as breath - a relationship implicit also in the word "spirit".
