How did Bapusaheb Buti react when Sai Baba fell seriously ill, and what were his concerns about the mansion?

When Sai Baba fell seriously ill and the end seemed near, Bapusaheb Buti became extremely uneasy and anxious about the fate of the mansion he was building. Chapter 39 describes how regret arose in him as he worried that lakhs of rupees had been spent, only for this great obstacle to appear. His heart was troubled by the thought that Baba's feet might never touch the temple. He questioned the very purpose of the building, wondering, "After Baba has left his body, what is the use of Murlidhar or the house?" This shows his deep distress and fear that his grand project would become meaningless without Sai Baba's presence.
