What does Chapter 7 say about Sai Baba's views on caste hierarchy and ritual purity?

Chapter 7 of the Shri Sai Satcharitra emphasizes that Sai Baba was completely beyond considerations of caste and ritual purity. It notes that for someone like Him, who had no ego regarding the body, there was no distinction between Hindu or Muslim, and caste did not matter in the slightest. The text provides powerful examples, stating that the 'best of Brahmins' and even ritually pure Agnihotris (keepers of the sacred fire) would abandon their pride and prostrate before Him. Furthermore, it's mentioned that His mind felt no disgust even if a dog were to put its mouth into the food, showing His complete detachment from conventional ideas of purity.
