Can you explain the symbolism of the wheat and the flour in the story where Baba was grinding to stop the cholera epidemic?

The symbolism in this story is explicitly explained in Chapter 1. The wheat that Baba was grinding was not food grain; it was a physical metaphor for the cholera epidemic that had afflicted the village. The act of grinding represented Baba's spiritual power actively destroying the disease, grinding the "enemy in the mill." Consequently, the resulting flour symbolized the vanquished, powerless remains of the epidemic. When Baba ordered the women to throw this flour on the village boundary, it was a symbolic act of casting the disease out of the community's borders. As the text confirms, once the flour was thrown near the stream, "the disease began to recede," and the "bad days ended."
