What was Balasaheb Deo's spiritual struggle, and what vow did he take because of it?

Balasaheb Deo had a deep desire to read the Dnyaneshwari daily, but he consistently encountered obstacles that prevented him from maintaining this practice. As described in Chapter 41, even when he took a three-month leave to focus on it, he found that doubts would arise in his heart, making the reading feel superficial and without love. He couldn't even manage to read five verses daily with regularity. Distressed by this failure, he made a firm resolution. He vowed that he would only begin reading the Dnyaneshwari again when Sai Baba Himself gave him a direct order, placing his faith entirely at Sai's feet to provide the necessary inspiration.
