Can you narrate the story of the Yoga practitioner who came to see Sai Baba with Nanasaheb Chandorkar in Chapter 23?

Certainly. Chapter 23 recounts the story of a Yoga practitioner who, despite being well-versed in Patanjali's Yoga Shastras, could not achieve Samadhi. Hoping Sai Baba, the 'King of Yogis,' could help, he visited the Masjid with Nanasaheb Chandorkar. However, upon seeing Baba eating stale bread with onions, a strong doubt arose in his mind about Baba's spiritual stature. As this chapter tells us, Sai Maharaj, being omniscient, immediately perceived his doubt and remarked to Nana, 'Only those whose digestion is strong should eat onion.' This profound statement startled the Yogi, who realized Baba knew his innermost thoughts. His doubt vanished, he surrendered with devotion, and he later received Baba's blessings with a clear and happy mind.
