Who promised to tell Balasaheb Deo the story of how he attained Sai's grace?

A person named Balkram was the one who promised to tell Balasaheb Deo the story of how he received Sai Baba's grace. Chapter 41 mentions that after Deo's first interaction with Baba regarding the twenty rupees, he met Balkram at night. Deo inquired about the 'previous account' of how Balkram had attained Sai's favor. In response to this inquiry, Balkram assured Deo, saying, 'Tomorrow after the Arati, I will tell everything to you.' Deo agreed to this, anticipating the story he would hear the following day.
