What spiritual text did Balasaheb Deo struggle to read, and what was the nature of his difficulty?

Balasaheb Deo had a great and persistent desire to read the Dnyaneshwari daily. As detailed in Chapter 41, his struggle was that despite his strong intent, some obstacle would always come up, preventing him from reading it regularly. Even when he took a three-month leave from work, he read other books but could not manage to read the Dnyaneshwari. When he did try, doubts would arise in his heart, which made the reading feel superficial and prevented him from developing a deep love for the text.
