Can you provide more details about the devotee Vrao, whose prayer is mentioned in Chapter 2?

The provided excerpts from Chapter 2 mention "vrao’s prayer" only once, as the catalyst for Sai Baba feeling compassion and deciding to authorize the writing of his stories. However, the text offers no further information about who Vrao was, the nature of his prayer, or his specific relationship with Sai. Immediately after this brief mention, the narrative in Chapter 2 shifts to Sai Baba's discourse on how the stories should be recorded, emphasizing that He Himself would be the true author, using the writer merely as a pretext. There are no other details about Vrao in these sections.
