How did Sai Baba view and interact with people of different castes and notions of purity?

Sai Baba completely transcended caste distinctions and conventional ideas of ritual purity. Chapter 7 illustrates that for him, caste did not matter in the slightest. The most respected and high-caste individuals, such as the best of Brahmins and keepers of the sacred fire (Agnihotris), would abandon their pride in ritual purity and prostrate before him. The text emphasizes that he had no ego regarding the body and was the same to all castes, with no distinction of birth. His indifference to social norms is highlighted by the example that his mind felt no disgust even if a dog put its mouth into the food, showing his profound detachment from worldly ideas of clean and unclean.
