On the basis of Kirlian effect (high frequency photography), a group of scientists led by Professor K.G.Korotkov (ITMO, St. Petersburg) developed a device called "GDV/EPC сamera" (Gas Discharge Visualization - Electro Photonic Capture camera). Kirlian photographs can show the energy condition of your systems and organs, psychological withdrawal or excess, emotional disharmony, unfulfilled potential, stress (both past and present), strength of will, suitability of living or working environment, circumstances or relationships, blocks, traits, strengths, thoughts and more. The device passed clinical tests, was included in the State Register of medical equipment certified by Russian Ministry of Health and is used around the world.
