This is Shiva, the dancer in a circle of fire.  As the Lord of Dance, Shiva performs the tandava, the dance in which the universe is created, maintained, and dissolved. The surrounding flames represent the manifest universe.

The symbolism reminds of T.S. Eliot’s “Burnt Norton” from the Four Quartets, one of the greatest literary works of the 20th century:

At the still point of the turning world. Neither flesh nor fleshless;
Neither from nor towards; at the still point, there the dance is,
But neither arrest nor movement. […] Except for the point, the still point,
There would be no dance, and there is only the dance.

And also William Gibson’s hauntingly powerful Count Zero, where the heroine finally converses with the lonely artificial intelligence:

“… your songs are sad.”
–My songs are of time and distance. The sadness is in you.  Watch my arms.  There is only the dance.  These things you treasure are shells.
“I–I knew that.  Once.”
