Can you describe the specific scene where Baba told Sapatnekar's life story to the shepherd woman?

Certainly. The event occurred after Sapatnekar, in a state of great distress, made a resolution to wait for Baba's grace. Chapter 48 details that he found a moment when Baba was alone on his cushion and took the opportunity to hold his feet. As Sapatnekar was massaging Baba's feet, a Dhangar (shepherd) woman arrived and sat down to rub Baba's waist. Baba then began a conversation with her. The miracle, as Sapatnekar listened, was that the story Baba was telling was his own. He was shocked to hear his entire life story, from birth to the death of his son, being narrated to this woman who had no connection to it.
