Describe the story of the Yoga practitioner who visited Sai Baba in Chapter 23. What was his problem, and how did Baba address his doubt?

Chapter 23 recounts the story of a practitioner of Yoga (Yogabhyasi) who, despite being well-versed in the Yoga Shastras, could not achieve Samadhi. Hoping the great yogi Sai Baba could help, he came for darshan but was immediately filled with doubt when he saw Baba eating bread with onions. The Yogi thought, "How can this man remove my doubts?" As Chapter 23 explains, the omniscient Sai Maharaj perceived this thought and remarked, "Nana, only those whose digestion is strong should eat onion." This profound statement startled the Yogi, who realized Baba knew his innermost thoughts. He surrendered with true devotion, his doubts were resolved, and he returned with a happy mind after receiving Udi and a blessing.
