Based on the provided text, why did Balasaheb Deo struggle with reading the Dnyaneshwari, and what was the turning point in his approach?

According to the account in Chapter 41, Balasaheb Deo's difficulty with the Dnyaneshwari was multifaceted. While he could read other books, whenever he took the Dnyaneshwari in hand, 'some doubts would arise in the heart.' This caused the reading to remain superficial, and he failed to develop a genuine love for the text. Despite a strong desire and repeated resolutions, some obstacle would always prevent him from maintaining a daily practice. The turning point came from his frustration. He made a new rule born of faith: he would completely cease his efforts and wait for Sai Baba to personally give him the order and inspiration to read it, thus surrendering his will to his Guru.
