Can you explain the story of the Yogabhyasi who came to see Sai Baba in Chapter 23?

Chapter 23 narrates the story of a practitioner of Yoga (Yogabhyasi) who visited Sai Baba with Nanasaheb Chandorkar. This yogi was well-versed in the Yoga Shastras of Patanjali but was frustrated because he could not achieve Samadhi (intense meditation) for even a moment. He came with the hope that Sai Baba, whom he considered a "King of Yogis," would show him grace, remove his doubts, and help him attain Samadhi. However, upon arriving at the Masjid for Baba's darshan, the Yogabhyasi was met with the sight of Baba simply eating bread (bhakar) with onions.
