Why was Bapusaheb Buti considered to have 'great luck' in relation to the mansion he built?

Bapusaheb Buti is described as having 'great luck' because the mansion he financed and built became the final resting place for Sai Baba's physical body. Chapter 39 explains that while Buti initially felt regret and anxiety when Baba fell ill, fearing the wada would be useless, a "stroke of fate and Sai’s command" led to an outcome of immense spiritual significance. Baba's last words, "Place me in the mansion," ensured that the structure would be eternally sanctified. The text states, "The mansion became the Samadhi Mandir; profound is Sai’s life story!" Buti's great fortune, therefore, was not in building a grand structure, but in having his personal property chosen by the Sadguru himself to be the Samadhi Mandir, a place of pilgrimage where the "holy body of Sai rests."
