How did Sai Baba eventually reveal his omniscience to Sapatnekar after repeatedly dismissing him?

Sai Baba revealed his all-knowing nature to Sapatnekar in a unique and indirect way. As detailed in Chapter 48, after Sapatnekar desperately held Baba's feet, a shepherd (Dhangar) woman arrived. Baba began a conversation with her, but the story he told was, miraculously, Sapatnekar's own life story. Sapatnekar listened in shock as Baba recounted his entire life, even mentioning the painful memory of his late son's death. The narrative made it clear that Baba knew everything about him, as if holding a gooseberry in the palm of his hand, filling Sapatnekar with wonder and immense respect.
