How did Balasaheb Deo's experience with reading different sacred texts highlight his specific problem with the Dnyaneshwari?

Chapter 41 illustrates a distinct contrast in Balasaheb Deo's reading habits. While he was able to read other books regularly and without issue, he faced a unique and persistent challenge with the Dnyaneshwari. The text states that even when he took a three-month leave to rest, he read other regular books but could not fulfill his desire to read the Dnyaneshwari. When he did attempt to read it, doubts would arise in his heart, making the reading feel superficial and preventing him from developing love for the text. This specific block towards the Dnyaneshwari, which was absent with other scriptures, led him to believe that a special grace from Sai Baba was needed to overcome it.
