How does Balasaheb Deo's story demonstrate the principle that Sai is particularly loving toward devotees with a 'true taste for spiritual matters'?

The narrative in Chapter 41 explains that Sai Baba is deeply affectionate towards devotees who have a genuine inclination for spirituality, helping them overcome difficulties to experience self-bliss. Balasaheb Deo's situation is presented as a prime example of this. His intense, albeit frustrated, desire to regularly study the Dnyaneshwari demonstrated his 'true taste for spiritual matters.' Although he struggled and failed on his own, his deep-seated spiritual longing is precisely the quality that the Satcharitra claims is very dear to Sai. The subsequent unfolding of events, starting with his vow to await Sai's command, is positioned as Sai's leela to fulfill the devotee's heartfelt spiritual wish.
