How did Sai Baba's attitude towards caste and ritual purity show that he was beyond social distinctions?

Sai Baba demonstrated a complete transcendence of social and ritualistic norms, particularly concerning caste and purity. Chapter 7 highlights that for someone like Baba who had no ego regarding the body, distinctions like Hindu or Muslim, or high and low caste, were meaningless. This is powerfully illustrated by the fact that the "best of Brahmins" and Agnihotris (keepers of the sacred fire) would abandon their pride in ritual purity and prostrate before Him. Furthermore, the text mentions that his mind felt no disgust even if a dog put its mouth into the food, showing a profound indifference to conventional ideas of defilement.
