What was the reaction of high-caste Brahmins and others to Sai Baba's enigmatic nature, as mentioned in Chapter 7?

According to Chapter 7, people from all walks of life were profoundly impacted by Sai Baba's presence, often reacting with awe and humility. The text specifically highlights the reaction of those from the highest Hindu castes. It states that even the 'best of Brahmins' and 'Keepers of the sacred fire (Agnihotris),' who might have taken pride in their ritual purity, would abandon their pride and prostrate before Him. As Chapter 7 eloquently puts it, people were amazed in their hearts, and whoever came to see the proof of His nature would end up behaving in the same way, becoming 'silent and humble upon seeing Him.' This demonstrates that His spiritual power transcended all social and religious hierarchies.
