The source says Sai instructed someone to feed a black dog. Who was it and for what reason?

The provided text from Chapter 41 does not contain any story about Sai instructing someone to feed a black dog. Instead, this chapter focuses on the story of a devotee named Balasaheb Deo and his specific spiritual struggle. He had a great desire to read the Dnyaneshwari daily but consistently faced obstacles that prevented him from doing so, even when he took a three-month leave to focus on it. His difficulty was so persistent that, as recounted in Chapter 41, he resolved to only begin reading it again when Sai Himself gave a direct order.
