The classical keraunos is still preserved in Tibet as the dorje, which is identified with Indra's thunderbolt, the vajra.
A letter was sent dorje Phagmo, asking if she would receive three British officers, including the antiquary of the expedition.
It often has half a dorje as a handle, or the handle is ornamented with various mystical symbols carved on it.
No wonder that the original dorje preserved at the Sera monastery has become an object of actual worship.
The handle is composed of a dorje (p. 322), and is surmounted by carvings of the heads of the three most powerful Dragsheds.
