Can you recount the story of the Yoga practitioner from Chapter 23 and explain why he initially had doubts about Sai Baba?

Chapter 23 narrates the story of a practitioner of Yoga (Yogabhyasi) who, despite being well-versed in the Yoga Shastras, was unable to achieve Samadhi. He sought Sai Baba's darshan, hoping the 'King of Yogis' could help him. However, a strong misgiving arose in his mind when he saw Baba eating bread (bhakar) with onions. As the chapter recounts, seeing this simple, worldly act of consuming stale bread and a dry onion made him think, "How can this man remove my doubts?" His doubt stemmed from a superficial judgment based on Baba's diet, which contradicted his preconceived notions of a great spiritual master.
