What was Sai Baba's attitude towards the caste system, and how did high-caste devotees react to him?

Chapter 7 explains that for Sai Baba, caste did not matter in the slightest degree. He was the same to all castes and made no distinction of birth, whether someone was considered a Shudra or an outcaste. The text emphasizes that he had no ego regarding the body and his mind felt no disgust. This radical equality had a profound effect on his devotees. As Chapter 7 notes, even the "best of Brahmins" and "Keepers of the sacred fire (Agnihotris)" would abandon their pride in ritual purity and prostrate before him. Upon seeing him, they would become silent and humble.
