What does Chapter 7 say about Sai Baba's attitude towards caste distinctions and ritual purity?

Chapter 7 emphasizes that Sai Baba completely transcended caste distinctions and notions of ritual purity. It states that for one who has no ego regarding the body, caste does not matter in the slightest. This is illustrated by the fact that the 'best of Brahmins' and even Agnihotris (keepers of the sacred fire) would abandon their pride in ritual purity to prostrate before Him. The text further explains that He was the same to all castes, with no distinction of birth, and His mind felt no disgust even if a dog put its mouth into the food, showing his complete detachment from social hierarchies.
