I've now seen the documentary film The Phenomenon Bruno Groening - On the tracks of the "Miracle Healer". It's a well made documentary. It's full of information, fascinating contemporary witness interviews and reenacted events.
The documentary is divided into three parts. It took 9 years to produce 5 hours of film. More than 2000 extras were involved, e.g. to reenact the famous events in Traberhof where mass healings took place. It's subtitled in 30 languages and the options for the voice track are German, English, French, Croatian, Polish, Russian and Spanish.
It is undeniably a fascinating documentary that I highly recommend!
You order the documentary from Grete Häusler Verlag. Currently, there´s no digital option to choose from. Together with the DVD, I ordered a booklet of 36 pages, The Teaching of Bruno Gröning (Introductory Set), with an introductory CD included. Here you´ll get information about how to do "einstellen" and read about, among other things, eye witness reports from Bruno Groening's life and success reports of today.
