How does Balasaheb Deo's struggle with the Dnyaneshwari exemplify Sai's relationship with devotees who have a 'true taste for spiritual matters'?

Balasaheb Deo's story is presented as a key example of Sai's love for sincere devotees. Chapter 41 explicitly states that Sai is especially affectionate towards those with a "true taste for spiritual matters," helping them overcome difficulties and giving them self-bliss. Deo's intense longing to read the Dnyaneshwari, a profound spiritual work, identified him as such a devotee. His struggle and ultimate surrender to Sai's will, vowing only to read upon His command, demonstrate immense faith. The narrative frames this as a situation where Sai would ultimately fulfill Deo's wish and grant him an "addition of devotion," showcasing the Guru's role in guiding a devotee past spiritual blockages.
