What was the miracle Sapatnekar witnessed involving the Dhangar woman, and why was it so significant for him?

The miracle Sapatnekar witnessed was a conversation between Sai Baba and a Dhangar (shepherd) woman who had come to massage his waist. As Sapatnekar listened carefully, he was shocked to realize that Baba was narrating his own life story in its entirety. According to Chapter 48, though the story was framed as being about a merchant, it was unmistakably his, even including the painful detail of his late son's death. The Dhangar woman had no connection to the events, making it clear the story was meant for Sapatnekar. This event was profoundly significant because it proved Baba's omniscience, filling Sapatnekar with wonder and etching a deep, lasting respect for Sai in his mind.
