Why was Balasaheb Deo unable to read the Dnyaneshwari, even though he could read other books without any problem?

The difficulty Balasaheb Deo faced with the Dnyaneshwari was unique and spiritual in nature. Chapter 41 explains that while other books could be read regularly, a specific block occurred with the Dnyaneshwari. Whenever he took it in hand, "some doubts would arise in the heart," which made the reading feel superficial and prevented him from developing a deep, heartfelt connection or "love" for the text. This was not a problem of literacy or discipline, as he could read other things. This persistent spiritual obstacle, unique to this scripture, is what led him to conclude that he required a direct command from Sai Baba to proceed.
