Does Chapter 10 mention anything about Baba's relationship with people of different faiths, like Hindus and Muslims?

Yes, Chapter 10 explicitly highlights Sai Baba's role as a unifier who transcended religious boundaries. The text poses the question of how great his public life was and answers by stating that Baba was 'a mother to both Hindus and Muslims.' This maternal comparison suggests his impartial love, care, and protection for all, regardless of their religious background. To further emphasize this point, Chapter 10 uses the powerful imagery that in his presence, 'the tiger and the lamb lived together in trust and love without doubt,' signifying that even natural enmities were resolved in the atmosphere of peace and unity he created.
