Why did Sai Baba suddenly start grinding wheat, and what was the villagers' reaction to this unusual act?

According to Chapter 1, Sai Baba unexpectedly began grinding wheat in the mosque, which filled the narrator's mind with wonder, as Baba was a detached saint with no possessions who lived on alms. Initially, people watched with curiosity, and no one dared to ask what he was doing. As the news spread, four women rushed to the mosque, took the handle from Baba, and began grinding themselves while singing his praises. Chapter 1 describes how Baba, after some feigned anger, smiled at their devotion. The villagers were initially puzzled by the act, but the women's participation turned it into a devotional event, though they misunderstood its ultimate purpose.
