How does the narrative about Balasaheb Deo's struggle with the Dnyaneshwari serve as an example of Sai Baba's leela?

The story of Balasaheb Deo is presented as a key example of Sai Baba's loving nature towards His devotees. Chapter 41 opens by stating that Sai is affectionate toward those with a 'true taste for spiritual matters' and helps them overcome difficulties. Deo's intense, yet thwarted, desire to read the Dnyaneshwari represents such a spiritual difficulty. His story, including his ultimate decision to wait for Sai's direct command, is framed as a leela that demonstrates how Sai tests and ultimately fulfills a devotee's wish, planning to give him an 'addition of devotion' in His own time and manner.
