Why did Balasaheb Deo feel his reading of the Dnyaneshwari was 'superficial'?

According to Chapter 41, Balasaheb Deo's difficulty with the Dnyaneshwari went beyond just external obstacles. When he did manage to take the book in hand, his efforts were hampered by internal issues. The text states that "some doubts would arise in the heart, Due to which the reading remained superficial; love did not arise within." This suggests that he wasn't able to connect with the text on a deep, emotional, or spiritual level. This lack of inner connection and the presence of doubt made the practice feel hollow, which ultimately led to his decision to surrender the effort until he received a clear sign and the necessary love for the text directly from Sai Baba.
