What was Sai Baba's attitude toward the caste system and concepts of ritual purity?

Sai Baba's approach was one of complete transcendence over caste and ritual purity, as detailed in Chapter 7. The text emphasizes that for him, caste did not matter "even in the slightest degree," and he was the same to all, making no distinction of birth whether someone was a Shudra or an outcaste. This is powerfully illustrated by the fact that the most esteemed Brahmins and keepers of sacred fires (Agnihotris) would abandon their pride in ritual purity and prostrate before him. Furthermore, Chapter 7 notes that Baba had no ego regarding the body and felt no disgust, even if a dog were to put its mouth into the food, showcasing his profound detachment from worldly notions of purity and impurity.
