What was the resolution Balasaheb Deo made regarding the Dnyaneshwari, and what was the immediate context of him revealing this to someone?

After numerous failed attempts to read the Dnyaneshwari daily, Balasaheb Deo became distressed and made a very specific resolution. As explained in Chapter 41, he decided with firm faith at Sai's feet that he would only read the Dnyaneshwari when Sai Baba Himself gave the order and instilled the love for it in his heart. The context for him revealing this was during a visit to Shirdi. He had traveled there on an auspicious occasion with his mother and sisters. While there, a person named Jog asked him directly, "Why aren't you reading Dnyaneshwari daily these days?" prompting Deo to explain his vow.
