How does the story of the Samadhi Mandir illustrate the concept that Sai's will can fulfill a devotee's purpose in an unexpected way?

The story powerfully illustrates this concept by contrasting the devotee's plan with the divine outcome. As told in Chapter 39, Bapusaheb Buti intended to build a temple for Murlidhar, but his heart grew anxious when Baba's passing seemed imminent, fearing his efforts were in vain. However, Baba had already prophesied, "we too shall come to stay there." The ultimate fulfillment of the mansion's purpose came not through Buti's plan but through Sai's final command: "Place me in the mansion." This turned Buti's despair into an eternal blessing, realizing the mansion's "great fortune" by making it the sacred resting place of Sai himself, a far greater honor than Buti could have imagined.
