How did Bapusaheb Buti's feelings about the mansion he was building change, and what ultimately happened to it?

Bapusaheb Buti initially planned to build a temple and mansion with an inner sanctum for an idol of Murlidhar. As Chapter 39 details, he was filled with regret and anxiety when Baba fell seriously ill, worrying that the lakhs of rupees spent would be wasted and that Baba's feet would never touch the temple. He felt the mansion would be useless without Baba. However, his fate turned around dramatically when Baba's last words were, "Place me in the mansion." Following this command, Baba's holy body was placed in the inner sanctum, transforming the mansion into the sacred Samadhi Mandir. This event is described in the text as the "great fortune" of the Buti wada, and the chapter praises the "luck of Buti" for having Shri Sai's body rest in his house.
