How does the narrative of Balasaheb Deo serve as an example of Sai's affection for his followers?

The story of Balasaheb Deo is presented as a prime example of Sai's love for his devotees. Chapter 41 explicitly states that those with a "true taste for spiritual matters are very dear to Sai," who helps them by "warding off all their difficulties." Deo's intense desire to read the Dnyaneshwari, despite his persistent failures, marked him as such a devotee. The narrative frames his struggle and ultimate success as a fulfillment of his wish by Sai, who not only removed the obstacles but also gave him an "addition of devotion."
