What's the story about Bhagwantrao Kshirsagar and why did Sai Baba say he was keeping him hungry?

The story of Bhagwantrao Kshirsagar, found in Chapter 4, illustrates Sai Baba's respect for ancestral traditions. Bhagwantrao's father was a devout worshipper of Vitthal, but after his father passed away, Bhagwantrao neglected the family's religious duties. He stopped the daily worship and food offerings (Naivedya) to the idol of Vitthal and even failed to perform the annual Shraddha ceremony for his father. When Bhagwantrao came to Shirdi, Baba, who called the father his friend, revealed that he had specifically drawn Bhagwantrao there to correct this. Baba stated, "He never offers food (Naivedya); he keeps me hungry too. He keeps Vitthal hungry too." This was Baba's way of reminding him of his duty and guiding him back to the path of devotion and remembrance his father had followed.
