Describe the interaction that led to the author receiving permission to write Sai Baba's life story, focusing on the theme of humility.

The process of gaining permission was steeped in humility from all involved. As detailed in Chapter 2, the author felt he lacked the courage to ask Baba directly, so he humbly relayed his desire through Madhavrao Deshpande. Madhavrao then approached Baba, who responded with his own profound humility, dismissing himself as a mere beggar whose story was not worth telling. Madhavrao, in turn, respectfully insisted on the story's value. This exchange culminated in Sai feeling compassion and granting his blessing. The entire event showcases the author's surrender of ego, Madhavrao's respectful persistence, and Baba's own egoless nature.
