Did Balasaheb Deo have trouble reading other spiritual texts besides the Dnyaneshwari?

Yes, the texts indicate a notable difference in Balasaheb Deo's ability to read various books. Chapter 41 states that he was able to read one chapter of the Bhagavad Gita daily as a rule. It also mentions that when he took other books in hand, they were read regularly. The Dnyaneshwari was the specific text that presented a persistent challenge. Despite his strong desire, some obstacle would always arise, and his resolution to read it would not hold, a problem he did not seem to have with his other regular readings.
