Can you provide a summary of the entire incident involving Baba and the wheat grinding?

Certainly. The incident, detailed in Chapter 1, begins with Baba preparing a grinding stone and measuring out wheat one morning. As a detached saint, his action of grinding caused great surprise. Villagers gathered, and four women rushed into the mosque, took the handle from Baba, and started grinding themselves while singing his praises. Baba's initial feigned anger turned into a loving smile. Once the grinding was done, the women speculated greedily, thinking that since Baba had no family and lived on alms, he must have ground the flour to distribute among them, each hoping for a share.
