How exactly did the Buti Wada transform from a Murlidhar temple into the Samadhi Mandir?

The transformation of the Buti Wada into the Samadhi Mandir was a direct result of Sai Baba's final command. Chapter 39 explains that while its builder, Bapusaheb Buti, was despairing over the building's fate due to Baba's illness, a pivotal moment occurred. Baba's last words were, "Place me in the mansion." This clear instruction from Baba himself resolved all uncertainty and fulfilled what the text calls the mansion's "great fortune." Following his passing, his holy body was placed in the inner sanctum, the very spot intended for the Murlidhar idol, thus consecrating the entire building as the Samadhi Mandir.
