Dorje Shugden
According to Joseph Rock there were two main Dorje Shugden oracles: Panglung Choje and Trode Khangsar Choje. Joseph Rock witnessed and documented a public invocation of the Panglung oracle in Kham (Eastern Tibet) in 1928. At this time the oracle took a sword of Mongolian steel and twisted into many loops. Choyang Duldzin Kuten Lama was the Dorje Shugden oracle for many years.
