What specific vow did Balasaheb Deo make at Sai Baba's feet regarding the Dnyaneshwari, and what was the catalyst for this decision?

After repeated failures and feeling distressed, Balasaheb Deo made a very specific and firm vow concerning his reading of the Dnyaneshwari. As detailed in Chapter 41, the catalyst was his inability to maintain any regularity in his reading, even when he resolved to read just five verses daily. This lack of success led him to make a rule for himself. He resolved from the heart, with faith at Sai's feet, that he would only start reading the Dnyaneshwari when Sai Baba himself gave the direct order and instilled the love for it in him. He declared, "Only when Sai gives the order, Then only will I read the Dnyaneshwari," and sat with this firm resolve, completely surrendering the initiative to his Guru.
