Could you explain the miracle Sapatnekar witnessed during the conversation with the Dhangar woman?

The miracle Sapatnekar witnessed was a profound display of Sai Baba's omniscience. As Sapatnekar was massaging Baba's feet, a Dhangar (shepherd) woman arrived and began talking with Baba. Chapter 48 of the Shri Sai Satcharitra recounts that as Sapatnekar listened, he was shocked to realize that every word of the story Baba was telling the woman was his own life story. Although framed as the story of a merchant (Wani), it detailed his life from birth, even including the painful news of his late son's death. The woman had no connection to the story, making it clear that Baba was communicating his all-knowing nature directly to Sapatnekar.
