What solemn vow did Balasaheb Deo make regarding the Dnyaneshwari, and what was the reason behind it?

After experiencing continuous failure in his attempts to read the Dnyaneshwari, Balasaheb Deo made a firm resolution. Chapter 41 explains that due to the persistent obstacles and a lack of inner love for the text when he tried to read it, he became very distressed. Consequently, he made a rule for himself: he would only begin reading the Dnyaneshwari again when Sai Baba Himself gave him a direct order and the love to do so. He placed his faith entirely at Sai's feet, deciding to sit with this firm resolve until he received that specific divine instruction.
