What specific assurances did Baba give to the author regarding his future and spiritual progress if he followed His instructions after retirement?

As detailed in Chapter 3, after the author retired in 1916, Sai Baba provided profound assurances for both his material and spiritual well-being. Materially, Baba promised that the author's "plates are always full; they will never be empty as long as he lives," removing his worries about providing for his family on a small pension. Spiritually, Baba promised that by performing His service with devotion, "his calamities will be removed" and that the "God of Gods will have mercy, and an eternal treasure will be found." This eternal treasure is linked to understanding Baba's true, omnipresent nature, which leads to the dissolution of all desires.
