What was Balasaheb Deo's primary spiritual struggle as described in the provided text?

Balasaheb Deo's main spiritual struggle was his inability to consistently read the Dnyaneshwari. As detailed in Chapter 41, despite having a profound desire to read it daily, he found that some obstacle would always arise, preventing his resolution from holding. This was a source of great distress for him, especially since he could read other books without issue. The text mentions that even when he took a three-month leave, he was unable to fulfill his wish to read the Dnyaneshwari. The reading felt superficial, and love for the text did not arise within him, causing his spiritual practice to falter.
