In what context is the story of Balasaheb Deo and the Dnyaneshwari introduced?

The story of Balasaheb Deo is introduced as an example of Sai Baba's profound love and affection for his devotees, especially those with a "true taste for spiritual matters." Chapter 41 explains that Sai wards off all difficulties for such devotees and gives them the company of self-bliss. Deo's experience is presented as a 'wager' or testament to this principle, illustrating how Sai Baba helps a devotee overcome a persistent spiritual obstacle—in this case, the inability to read the Dnyaneshwari—and adds to their devotion, showcasing Sai's marvelous Leela.
