What is the story of the Yogi and Nanasaheb Chandorkar in Chapter 23, and what does it teach about judging a saint?

Chapter 23 recounts the story of a practitioner of Yoga who, despite studying the Yoga Shastras, could not achieve Samadhi. He accompanied Nanasaheb Chandorkar to visit Sai Baba, hoping the 'King of Yogis' could help him. However, his faith wavered when he saw Baba eating stale bread with onions, causing him to think, 'How can this man remove my doubts?'. As described in the chapter, the omniscient Sai Baba immediately addressed the Yogi's unspoken thought by stating, 'only those whose digestion is strong should eat onion.' This startled the Yogi, dissolving his doubt and leading him to surrender completely. The story powerfully illustrates the teaching that a saint's true state is beyond external appearances like diet and that one should not pass judgment based on such superficial observations.
