Four Animal-Headed Guardian Dakinis

Tib., sgo ma bzhi: Four Gate Mothers

These 'Guardians of the Four Gates of the Mandala', aka the 'four female gate keepers', appear on the 6th day of the bardo (not to be confused with the four Vajra-guardians who appear on the 12th day).

Their names reflect the symbolic tool or weapon they hold in their hands; and all of the deities appear surrounded by flames and wearing a tiger skin. They symbolize/represent certain methods and manners of being reborn when emerging from the bardo:

Evans Wentz gives Kinkinidhari instead of Ghanta.
Thurman gives Spotha (a synonym for the chain shrinkhala) instead of Vajrasrinkhala, and the short Pasha rather than Pasadhari.
