How did Balasaheb Deo's experience reading the Dnyaneshwari differ from his experience with other books?

According to the narrative in Chapter 41, there was a stark contrast in Balasaheb Deo's reading experiences. When he took up other books, he was able to read them regularly and without any particular issue. However, the Dnyaneshwari was a unique exception. Despite his strong intention to read it daily, he consistently failed. Obstacles would always appear, his resolution would break, and he couldn't even maintain the simple practice of reading five verses a day with regularity and enthusiasm. This specific and persistent difficulty with the Dnyaneshwari, which was not present with other texts, is what caused him so much inner turmoil.
