What was the specific nature of the difficulty Balasaheb Deo experienced when attempting to read the Dnyaneshwari?

According to the narrative in Chapter 41, Balasaheb Deo's struggle with the Dnyaneshwari was internal. Whenever he took the book in hand, doubts would arise in his heart. This caused the reading to feel superficial, and as a result, a genuine love for the text did not arise within him. This internal conflict was so persistent that his resolution to read it failed, and he found he could not even manage to read a mere five verses, or Ovis, with regularity and enthusiasm, leaving him feeling distressed.
