Can you detail the encounter with the practitioner of Yoga as described in Chapter 23, including his doubt and its resolution?

Chapter 23 recounts the story of a practitioner of Yoga (Yogabhyasi) who had thoroughly studied the Yoga Shastras but could not achieve Samadhi. Believing Sai Baba, the King of Yogis, could help him, he came for darshan. However, his conviction was shaken when he saw Baba eating stale bread with onions, which caused a strong misgiving to arise in his mind about Baba's spiritual abilities. As described in Chapter 23, the omniscient Sai Maharaj immediately addressed the man's unspoken thought by saying, "only those whose digestion is strong should eat onion." This 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 Baba's blessings.
