Can you explain the strange conversation Sai Baba had with a Dhangar woman that involved Sapatnekar?

While Sapatnekar was massaging Sai Baba's feet, a Dhangar (shepherd) woman arrived and began rubbing Baba's waist. Baba then started a conversation with her, which, on the surface, was about a merchant (Wani). However, as Sapatnekar listened carefully, he was shocked to find that every word of the conversation was actually his own life story. Chapter 48 of the Shri Sai Satcharitra explains this miracle, noting that the story included intimate details, even the news of his late son's death. Though the Dhangar woman was the apparent audience, the narrative was entirely for Sapatnekar, leaving him filled with wonder at Baba's omniscience.
