How did Bapusaheb Buti react when Sai Baba fell gravely ill, and what were his specific concerns about the mansion he was building?

When Sai Baba fell seriously ill and his end seemed near, Bapusaheb Buti became deeply distressed and uneasy. Chapter 39 describes his anxiety, as he feared his grand project would be for nothing. He lamented, "Will Baba's feet ever touch this temple now? Lakhs of rupees have been spent, and in the end, this obstacle has come." Buti's heart was troubled with the thought that after Baba's passing, the mansion and the Murlidhar temple would be useless. His regret stemmed from the belief that the building's spiritual purpose, to be blessed by Baba's presence, would be unfulfilled.
