How did Damu Anna demonstrate his devotion to Sai Baba, and what were the results of his faith?

According to Chapter 25, Damu Anna, a wealthy and devout person from Ahmednagar, expressed his devotion through consistent acts of faith. One significant example was his vow to provide one of the two large new flags for the annual Ram Navami festival procession in Shirdi, a vow he upheld with uninterrupted love for many years. The text highlights that once one-pointed faith is established, Sai Baba wards off misfortunes. As a direct result of Sai's blessings, Damu Anna, who had been childless despite having two wives, was blessed with sons, demonstrating how Sai grants the desired objects of His devotees.
