What was Sai Baba's stance on the caste system and concepts of ritual purity?

Sai Baba completely transcended the social constructs of caste and ritual purity, as detailed in Chapter 7. The text emphasizes that for him, "caste did not matter even in the slightest degree" and he was the same to all, whether they were Shudra, outcaste, Hindu, or Muslim. This was evident in how people of all backgrounds were drawn to him; even the "best of Brahmins" and Agnihotris (keepers of sacred fire), who were traditionally very conscious of ritual purity, would abandon their pride and prostrate before him. The chapter further illustrates his detachment from bodily ego and purity rules by noting that his mind felt no disgust even if a dog were to put its mouth in the food, showing his profound state of equality and non-distinction.
