Scene from the Bhuridatta Jataka.
In the hidden depths of the earth, far below the fields and woodlands of the world of men, dwell the nagas. They are magical serpents who can assume human form when they wish. Their kingdom glitters with rare jewels and precious minerals as they live in great splendor and richness.
From time to time, they leave their realm and mingle with the human beings who inhabit the surface of the earth. The archenemy of the naga is the garuda, the great bird who lives in the sunlit and airy skies.
