How did Sai Baba directly address Sapatnekar's unspoken grief and accusation regarding his son's death?

After indirectly narrating Sapatnekar's life story, Sai Baba demonstrated his ability to know a person's innermost thoughts. Chapter 48 recounts how Baba, knowing Sapatnekar was thinking he was a great knower of the inner self, suddenly pointed at him and exclaimed, "He says I killed his child; he is accusing me of this!" Baba then immediately comforted him, denying that he kills people's children and promising to bring a son back to his lap, just as he had for another devotee. By placing his hand on Sapatnekar's head and telling him his worry was gone, Baba directly addressed and soothed his deepest, unvoiced sorrow.
