Can you explain the strange conversation Baba had with the shepherd woman and what it meant for Sapatnekar?

After Sapatnekar held Sai Baba's feet, a Dhangar (shepherd) woman arrived and began massaging Baba's waist. Baba then started a conversation with her. As Sapatnekar listened, he was shocked to realize that the story Baba was telling was his own life story. Shri Sai Satcharitra Chapter 48 explains this miracle in detail. Although the story was ostensibly about a merchant, or Wani, every word pertained to Sapatnekar's life, from his birth and even including the painful memory of his late son's death. The Dhangar woman had no connection to the story and just kept saying "Yes," making it clear that the entire conversation was orchestrated for Sapatnekar's benefit, revealing Baba's omniscience and profound connection to his devotee.
