When Baba fell seriously ill, what specific anxieties did Bapusaheb Buti have regarding the mansion he was building?

As Sai Baba's health declined, Bapusaheb Buti became deeply uneasy and anxious about the fate of the mansion he was constructing. Chapter 39 details his troubled thoughts. Buti worried about what would become of the mansion and feared that Baba's feet would never touch the temple. He felt a sense of regret, thinking that the lakhs of rupees spent would be wasted. His primary concern was that if Baba were to leave his body, the mansion, the temple, and the planned Murlidhar idol would all become useless. This potential obstacle after so much effort caused his heart to be deeply troubled.
