How did Sai Baba show that he was beyond caste distinctions and ritual purity?

Sai Baba's life was a clear demonstration of his transcendence of caste and ritual purity rules. Chapter 7 illustrates that for him, caste did not matter in the slightest, whether one was a Shudra or from any other social standing. The most respected and ritually pure Brahmins and Agnihotris (keepers of sacred fire) would abandon their pride and prostrate before him. The text provides a powerful example of his detachment from notions of purity, stating that his mind felt no disgust even if a dog were to put its mouth in the food, showing he was completely free from ego regarding the body and societal norms.
