What was Sai Baba's attitude towards the caste system and social purity?

Sai Baba completely rejected distinctions based on caste or social status. Chapter 7 emphasizes that for one who has no ego regarding the body, caste did not matter in the slightest. The text notes that the most revered Brahmins and Agnihotris (keepers of the sacred fire) would abandon their pride in ritual purity and prostrate before him. This shows that his spiritual presence made such social hierarchies irrelevant. His impartiality was so profound that his mind felt no disgust even if a dog were to eat from the same food, demonstrating his complete detachment from worldly ideas of purity and impurity.
