According to the narrative of Balasaheb Deo, what is the significance of having a 'true taste for spiritual matters' for a devotee of Sai Baba?

Chapter 41 uses Balasaheb Deo's story to illustrate a key principle: "Those who have a true taste for spiritual matters are very dear to Sai." Deo's persistent, intense desire to read the Dnyaneshwari, despite his repeated failures, is presented as evidence of this 'true taste.' The significance is that this sincere spiritual yearning attracts Sai's grace. The text suggests that Sai actively helps such devotees by "Warding off all their difficulties, He gives them the company of self-bliss." Deo's ultimate decision to place his faith entirely at Sai's feet, waiting for His order, shows that his spiritual longing was deep enough to lead to complete surrender, the very condition that invites the Guru's intervention to overcome such obstacles.
