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

Chapter 7 emphasizes that Sai Baba was completely beyond all distinctions of caste and ritual purity. The text highlights that even the "best of Brahmins" and prideful Agnihotris (keepers of the sacred fire) would prostrate before him, abandoning their notions of ritual superiority. It explicitly states, "For one who has no ego regarding the body, whether Hindu or Muslim, He was the same to all castes; there was no distinction of birth for Him." His transcendence of purity norms is further illustrated by the fact that his mind felt no disgust even if a dog were to put its mouth in the food, demonstrating his profound equanimity and focus on the divine over worldly customs.
