What was Sai Baba's attitude towards caste distinctions and ritual purity as described in the Satcharitra?

Chapter 7 of the Shri Sai Satcharitra clearly indicates that Sai Baba had no regard for caste distinctions or conventional notions of purity. The text states that for one who has no ego regarding the body, like Baba, distinctions of Hindu or Muslim, Shudra or outcaste, did not matter in the slightest. This is proven by the fact that the most revered Brahmins and keepers of the sacred fire (Agnihotris) would abandon their pride in ritual purity and prostrate before Him. The chapter further illustrates his detachment from such norms by noting that His mind felt no disgust even if a dog were to put its mouth in the food, showing He was the same to all castes and beings.
