It is a representation of Trimurti, a fusion of Brahma, Vishnu and Shiva, personifying union of the forces of creation, sustenance and destruction. Brahma is rajasic, active and energetic; Shiva is tamasic, passive and inert; Vishnu on the other hand is sattvic, constantly trying to create a balance between the aggressiveness of the creator and the regressiveness of the destroyer. Together they represent the trinity and are the most important group in the Hindu pantheon.
The artist has achieved the calm expression on the faces with the help of colours from the ochre family. A white halo surrounds the bust, followed by brick red above and brown below. The crackle effect shows very well on the red, encompassing the serene image.
