Why did Bapusaheb Buti get so worried when Sai Baba fell ill towards the end of the wada's construction?

Bapusaheb Buti became deeply uneasy and anxious when Sai Baba fell seriously ill because he feared the entire project would become meaningless. As Chapter 39 explains, Buti was tormented by the thought, "Will Baba's feet ever touch this temple now?" Having spent lakhs of rupees, he saw Baba's impending passing as a major obstacle that would render the building useless. His heart was troubled because he believed that without Baba's presence, the mansion, the temple, and the planned Murlidhar idol would have no purpose. The entire value of his grand undertaking was tied to Sai Baba's personal use of the space.
