What was the specific vow Balasaheb Deo made to Sai Baba concerning the Dnyaneshwari, and why did he feel it was necessary?

After being repeatedly thwarted in his attempts to read the Dnyaneshwari, Balasaheb Deo felt distressed and concluded that he could not succeed by his own efforts. As a result, he made a very specific and firm vow. The account in Chapter 41 states that he resolved, "Only when Sai Himself gives love And says 'Read,' then will I start without any confusion." He felt this was necessary because his personal resolutions consistently failed, and even the simple goal of reading five verses daily was not met with regularity. He therefore surrendered his own will in the matter and decided to wait for a direct, unambiguous command from Sai Baba before he would attempt to read the sacred text again.
