1750 (ca.), [Central Tibetan], Six-Armed Mahakala [watercolor] -- Virginia Museum of Fine Arts (Richmond)

From the museum label:

 

Mahakala's emanations are so numerous that even a particular form may appear in multiple variations. Closely associated with the six-armed, white Mahakala to the left, this blue-black variant is linked not with wealth but with removing obstacles. Like the white version, however, he is understood to be a wrathful form of Avalokiteshvara. As such, the rosary of human skulls he brandishes in his upper right hand is a frightening transmutation of the crystal meditation beads that the peaceful bodhisattva holds in that same hand. His flaming nimbus--and those of his five fearsome attendants--interrupts the verdant landscape, as do gruesome offerings in skull bowls and small scenes of animals devouring corpses. In the clouds above floats the Great Adept Shavaripa, probably an important figure in the spiritual lineage of the painting's patron.
