What is "abd-ru-shin"

Oskar Ernst Bernhardt, also known as Abd-ru-shin or Abdruschin (18 April 1875, Bischofswerda, Kingdom of Saxony, German Empire - 6 December 1941, Kipsdorf, Ore Mountains, Germany), is best known as the author of the Grail Message.

After a brief commercial training Oskar Ernst Bernhardt began his literary activity while still a young man. This often led him to foreign countries. In 1915 he was interned in England. Released in 1919, he first went to Dresden, later to Bavaria and in 1923 began to write the first lectures of the Grail Message.

In 1928 he settled in Vomperberg, Tyrol. There he wrote "In the Light of Truth: The Grail Message". He was labeled a "dangerous" element by the Nazi authorities and exiled from Austria in 1938. He was kept under surveillance until his death in 1941.
