Can you explain the symbolic connection between Baba grinding wheat and the disappearance of the cholera epidemic?

The act of grinding wheat was a symbolic and miraculous play by Sai Baba to save the village. Chapter 1 reveals that the wheat Baba was grinding was not actually grain but a representation of the cholera epidemic that was plaguing the area. By grinding the 'wheat' into 'flour' in the mill, he was symbolically crushing the disease itself. He then instructed the women to throw this 'flour' on the village boundary near a stream. This act completed the process of driving the epidemic out of the village. As Chapter 1 explains, after the flour was thrown, the disease began to recede, demonstrating an 'inconceivable cause and effect' that was part of Baba's divine skill.
