What specific spiritual text did Balasaheb Deo struggle to read, and what was his experience when he tried to read other books?

Balasaheb Deo had a great desire to read the Dnyaneshwari daily, but he consistently faced obstacles that prevented him from doing so. Chapter 41 explains that despite his strong intent, his resolution to read it would not hold without interruption. In contrast, when he took other books in hand, they were read regularly. This difficulty was unique to the Dnyaneshwari. Even when he took a three-month leave from his job, he managed to read other regular books but could not fulfill his desire to read the Dnyaneshwari, as its time did not seem to come.
