What was Sai Baba's perspective on caste and social hierarchy?

As described in Chapter 7, Sai Baba's perspective was one of complete indifference to caste and social status. The text explicitly states that for one who has no ego regarding the body, caste did not matter in the slightest. This is illustrated by the fact that the 'best of Brahmins' and keepers of sacred fires (Agnihotris) would abandon their pride in ritual purity and prostrate before Him. He treated all castes the same, whether Shudra or outcaste, showing no distinction of birth and feeling no disgust, even in situations that would challenge conventional purity norms.
