Based on Chapter 7, analyze Sai Baba's perspective on caste distinctions and ritual purity.

Chapter 7 provides a profound insight into Sai Baba's complete transcendence of caste and ritual purity norms. It states that for one who is surrendered to God, caste—be it Shudra or outcaste—mattered not in the slightest. This is powerfully illustrated by the fact that the "best of Brahmins" and even Agnihotris, who are keepers of the sacred fire and traditionally adhere to strict purity rules, would abandon their pride and prostrate before him. The most striking example of his mindset is the mention that if a dog put its mouth into the food, Baba's mind felt no disgust. This demonstrates his egoless state regarding the physical body and his view that all beings were equal, rendering the social constructs of caste and external purity meaningless in his presence.
