Why is Bapusaheb Buti described as having 'great luck' and his house having its 'great fortune realized'?

Bapusaheb Buti is considered to have 'great luck' because the mansion he constructed became the final resting place of his Sadguru, Sai Baba. As Chapter 39 explains, while Buti was deeply worried that his expensive mansion would be purposeless after Baba's passing, a twist of fate, or 'Sai’s command,' changed everything. Baba's last words instructed that he be placed in the mansion. Consequently, the structure's 'great fortune was realized' as the holy body of Shri Sai came to rest in Buti's own house. This transformed his personal project into an eternally holy shrine, the Samadhi Mandir, which is why the text declares, 'Blessed is the luck of Buti.'
