What does chapter 7 say about Sai Baba's views on the caste system and ideas of ritual purity?

Chapter 7 makes it clear that Sai Baba was entirely unconcerned with distinctions of caste or notions of ritual purity. The text states that for someone like him, who was always surrendered to God, caste did not matter in the slightest. He was the same to all, whether they were Brahmins, Shudras, or outcastes. This chapter provides a powerful example of his detachment from purity norms, noting that his mind felt no disgust even if a dog were to put its mouth in the food. This profound equality was so evident that even the highest caste Brahmins and Agnihotris (keepers of sacred fire) would abandon their pride and prostrate before him.
