What was Sai Baba's attitude towards caste distinctions and ritual purity as described in the text?

Chapter 7 reveals that Sai Baba was completely beyond all considerations of caste and ritual purity. The text states that for one surrendered to God like Him, caste did not matter in the slightest, whether one was considered a Shudra or an outcaste. This is powerfully illustrated by the fact that the most elite Brahmins and Agnihotris (keepers of the sacred fire) would abandon their pride in ritual purity and prostrate before Him. His detachment was also shown in his lack of disgust, as the text notes that His mind would feel no revulsion even if a dog were to put its mouth in the food, demonstrating His equanimity and lack of ego regarding the body.
