I've heard that Baba was unconcerned with social norms. Is there an example of this in his daily routine?

Yes, Chapter 0 provides a powerful example of this through his daily interaction with Bhagoji Shinde. Bhagoji, who was afflicted with leprosy, would tend to Maharaj every morning. This service included untying bandages on Maharaj's hand, massaging his body, and even sharing a chillum (a pipe). The text explicitly highlights that 'Maharaj never felt disgust for him nor changed his daily routine regarding him one bit.' This demonstrates a complete disregard for conventional fears and social stigmas surrounding disease, prioritizing compassion and devotion over social norms.
