Can you explain the miracle that occurred with Sapatnekar and the Dhangar woman at the mosque?

The miracle involving Sapatnekar and the Dhangar (shepherd) woman is a profound demonstration of Sai Baba's omniscience. As described in Chapter 48, while Sapatnekar was massaging Baba's feet, a shepherd woman arrived. Baba began conversing with her, but Sapatnekar, listening carefully, was shocked to realize that Baba was narrating his own life story in its entirety. The story, though seemingly about a merchant, recounted private details from Sapatnekar's life, including the painful news of his late son's death. This astounded Sapatnekar, as the woman had no connection to his life, proving that Baba was revealing his intimate knowledge for Sapatnekar's benefit.
