Can you detail the specific challenges Balasaheb Deo encountered while trying to study the Dnyaneshwari and how this differed from his other reading habits?

According to the account in Chapter 41, Balasaheb Deo's challenge with the Dnyaneshwari was unique and persistent. While he successfully read other books, including a chapter of the Bhagavad Gita daily, his resolution for the Dnyaneshwari would invariably be interrupted. The text explains that whenever he picked up the Dnyaneshwari, doubts would surface in his heart, making the reading feel superficial and preventing him from developing a true love for it. This problem persisted even when he took a three-month leave from work, a time when he was able to read other books but still found that the 'time did not come' for the Dnyaneshwari.
