Why did Bapusaheb Buti get so worried about the mansion when Sai Baba fell seriously ill?

Bapusaheb Buti became deeply uneasy and anxious when Baba fell seriously ill because he feared his entire project would be for naught. According to chapter 39, he lamented the lakhs of rupees spent, worrying that Baba's feet might never touch the temple. His heart was troubled by the thought that after Baba's passing, the mansion and the Murlidhar idol would be useless. This regret and fear stemmed from his devotion to Sai, believing the structure's value was entirely dependent on Baba's presence and blessing.
