The Satcharitra describes the Buti Wada as having 'great fortune'. How was this fortune realized and what did it entail?

The 'great fortune' of the Buti Wada, as explained in Chapter 39, was its ultimate destiny to house the sacred body of Shri Sai, thereby becoming the holy Samadhi Mandir. This fortune was realized through what the text describes as a "stroke of fate and by Sai’s command." Despite Bapusaheb Buti's fear that the building would be meaningless, Baba's final words, "Place me in the mansion," changed its fate entirely. The fortune entailed the mansion being elevated to an exceedingly holy status, far greater than its original purpose as a temple for Murlidhar. The text describes Buti's luck as blessed because the physical form of Sai came to rest in his own house, ensuring its perpetual sanctity.
