Can you explain the miracle Sapatnekar witnessed involving the Dhangar woman and how it related to him personally?

The miracle Sapatnekar witnessed was a profound display of Sai Baba's omniscience. As mentioned in Chapter 48, while Sapatnekar was massaging Baba's feet, a Dhangar (shepherd) woman arrived and began massaging Baba's waist. Baba started a conversation with her, seemingly about a merchant (Wani). However, as Sapatnekar listened, he was shocked to realize that every word of the conversation was actually his own life story. Baba narrated events from Sapatnekar's birth until that moment, even including the painful news of his late son's death. This indirect narration was meant entirely for Sapatnekar, demonstrating that Baba knew his innermost life details completely.
