Shri Devi with Yantra (Magic Circle).
The circular diagram in the belly of the blue Glorious Goddess is a magical device called a yantra. Just like a magic charm found in cultures throughout the world, the basic symbol is a lotus shape with a black center and four red petals surrounding, with an outer ring edged by flames. The three sections of the circle are inscribed with different protective verses, imprecations and curses aimed at enemies and misfortune.
An object such as this would be created based on a perceived threat followed by a divination ritual to determine the best course of action. Based on the outcome of the divination an artist would be commissioned to create a specific painting. Upon completion the painting might be used in further protective ceremonies, but more likely the act of creating the image itself and hanging it serve as the protective remedy.
