What vow did Balasaheb Deo make to Sai Baba regarding the Dnyaneshwari?

Frustrated by his repeated failures to read the Dnyaneshwari, Balasaheb Deo made a specific and firm vow. As detailed in Chapter 41, he resolved from the heart that he would not attempt to read the sacred text on his own any longer. Instead, he decided he would only start reading the Dnyaneshwari when Sai Baba Himself gave the order and the love to do so. He stated, "Only when Sai gives the order, Then only will I read the Dnyaneshwari." This act demonstrated his complete surrender to his Guru's will for his spiritual progress.
