How does the story of Balasaheb Deo demonstrate Sai's method of helping devotees overcome their spiritual difficulties?

The story of Balasaheb Deo, as narrated in Chapter 41, illustrates how Sai Baba helps devotees with a true taste for spiritual matters. The text explicitly states that Sai wards off their difficulties and gives them self-bliss. Deo was struggling with a spiritual obstacle, his inability to read the Dnyaneshwari. Instead of a simple solution, Deo's journey involved making a firm resolve to await Baba's command. His subsequent interactions in Shirdi, including Baba asking him for twenty rupees on two separate occasions, are presented as part of Baba's loving way of engaging with the devotee to ultimately fulfill his wish and give him "the addition of devotion."
