Yes. The original similar concept is called TENS. Oldest, uses electric current simulation. The other concept was using sound interaction with brainwave monitoring - monaural and binaural beats. There are also light based variants. Yet other used magnetic fields and another is called tDCS. There is also hypnosis, pretty old. These have nothing in common with religion yet are similar to meditation when measured... not exactly identical of course. I'm quite sure someone would figure out a link between specific thought patterns and physiology in a specialized field like neuroscience...
