Can you recount the story of the Yoga practitioner who visited Sai Baba hoping to achieve Samadhi?

Certainly. Chapter 23 tells of a practitioner of Yoga (Yogabhyasi) who was well-versed in the Yoga Shastras of Patanjali but struggled to achieve Samadhi, or intense meditation. Believing that the "King of Yogis" Sai Baba could grant him this experience, he came to the Masjid for darshan with Nanasaheb Chandorkar. He held a strong intent in his heart that Baba's grace would resolve his doubts. However, upon his arrival, he was taken aback to see Sai Baba engaged in the very ordinary act of eating bread (bhakar) with onions, a simple sight that contrasted with his expectations of a great yogi.
