After the author's government service ended in 1916, what specific promise did Sai Baba make regarding his financial situation, and what was the main condition for this promise to be fulfilled?

Following the completion of his government service in 1916, the author's friend, Anna Chinchonikar, expressed concern to Sai Baba about the author's financial stability given his small pension and growing household. As Chapter 3 narrates, Sai Baba offered a powerful assurance. The promise was that the author's material needs would always be met, as Baba declared, "His plates are always full; they will never be empty as long as he lives." The primary condition attached to this divine guarantee was a shift in focus from worldly pursuits to spiritual service. Baba instructed, "Now he should do my service; he will find happiness in the household." Therefore, the fulfillment of the promise of material security was contingent upon the author performing Baba's service with devotion and feeling, which would also remove his calamities and lead to an 'eternal treasure.'
