How did Sai Baba reveal Sapatnekar's life story in a miraculous way?

After Sapatnekar endured a period of being rebuffed, he finally approached Baba and held His feet. At that moment, a shepherd (Dhangar) woman arrived and Baba began a conversation with her. Chapter 48 of the Shri Sai Satcharitra recounts the miracle that followed: Sapatnekar, who was listening, realized that Baba was narrating his own life story in its entirety, framing it as the story of a merchant. The account was shockingly accurate, even mentioning the death of Sapatnekar's late son. Through this indirect method, Baba revealed his omniscience and deep knowledge of Sapatnekar's past, proving that He knew everything about him.
