In Shirdi, who approached Balasaheb Deo to ask him why he wasn't reading the Dnyaneshwari?

The person who questioned Balasaheb Deo in Shirdi was Jog. After Deo had become so distressed with his inability to read the Dnyaneshwari that he resolved to wait for a direct order from Sai Baba, he traveled to Shirdi. As stated in Chapter 41, it was there that Jog asked him, "Why aren't you reading Dnyaneshwari daily these days?" This question directly touched upon the very spiritual struggle that Deo had surrendered at Sai's feet, setting the stage for the Guru's leela.
