How did Bapusaheb Buti's feelings change from the start of the construction to when Baba fell ill?

Initially, Bapusaheb Buti was hopeful, securing Sai Baba's joyful permission to build a temple for Murlidhar. However, as Chapter 39 describes, his feelings turned to anxiety and regret when Baba fell seriously ill. Bapusaheb became uneasy, wondering what would become of the mansion. He lamented the lakhs of rupees spent, fearing Baba's feet would never touch the temple and feeling that the mansion would be useless after Baba left his body. His heart was deeply troubled by this unforeseen obstacle.
