energy (esotericism)

The term energy is used by writers and practitioners of various esoteric forms of spirituality and alternative medicine to refer to a variety of phenomena. There is no scientific evidence for the existence of such energy. Therapies that purport to use, modify, or manipulate unknown energies are thus among the most contentious of all complementary and alternative medicines. Claims related to energy therapies are most often anecdotal, rather than being based on repeatable empirical evidence.
