How did Sai Baba reveal his omniscience to Sapatnekar in a miraculous way?

After resolving to wait for Baba's grace, Sapatnekar found an opportunity when Baba was alone and clasped his feet. At that moment, a Dhangar (shepherd) woman arrived. As described in Shri Sai Satcharitra Chapter 48, Baba began a conversation with her, but the subject of the talk was a miracle in itself. Sapatnekar listened carefully and was shocked to realize that Baba was narrating his own complete life story, framed as the story of a merchant. Baba recounted everything from Sapatnekar's birth to the death of his late son, demonstrating that everything was clear to Him. The woman had no connection to the story, making the event a profound and personal revelation for Sapatnekar.
