What was the specific turning point that made Sapatnekar's frustration with Sai Baba turn into deep reverence?

The pivotal moment for Sapatnekar is detailed in Chapter 48 of the Shri Sai Satcharitra. After resolving to wait for Baba's grace despite his distress, he seized an opportunity when Baba was alone to hold his feet. As he did so, a shepherd woman arrived. The turning point occurred as Sapatnekar listened to Baba engage in a conversation with this woman. He was shocked to realize that the story Baba was telling her was, in fact, his own complete life story, from birth to the death of his son. Hearing his intimate history from Sai's mouth filled him with "great wonder," and this miraculous proof of Baba's omniscience instantly etched "deep respect for Sai’s feet" in his mind.
