Can you recount the story from Chapter 23 about the Yoga practitioner who came to see Sai Baba?

Certainly. Chapter 23 tells of a practitioner of Yoga (Yogabhyasi) who, accompanied by Nanasaheb Chandorkar, came for Sai Baba's darshan. This man had thoroughly studied the Yoga Shastras of Patanjali but was unable to achieve Samadhi (intense meditation) for even a moment. He came with the hope that Sai, as a "King of Yogis," would show him grace and help him achieve his goal. However, upon taking darshan in the Masjid, he did not witness a grand spiritual display. Instead, he saw Sai Baba simply eating bread (bhakar) along with onions, which challenged his preconceived notions.
