Dorje Shugden
Dorje Shugden oracles were once consulted by the Dalai Lamas until the 14th Dalai Lama banned the practice, even though he consulted Dorje Shugden for advice to escape and was successful in it. Due to the ban, many of the abbots that were worshippers of Dorje Shugden have been forced to go against the Dalai Lama.
