How did Sai Baba uniquely reveal Sapatnekar's life story back to him?

Sai Baba used a miraculous and indirect method to reveal His omniscience to Sapatnekar. As detailed in Chapter 48, while Sapatnekar was massaging Baba's feet, a Dhangar (shepherd) woman arrived and sat down. Baba then began a conversation with this woman, but the content of the conversation was, astonishingly, Sapatnekar's own life story. Although framed as the story of a merchant, every detail, including the tragic death of Sapatnekar's late son, was recounted. Sapatnekar listened in shock as the woman simply replied "Yes," realizing that Baba was narrating his entire life to him through this seemingly unrelated conversation.
