Chapter 23 mentions that a saint's true nature is hard to understand. Can you explain this concept using the details provided?

Chapter 23 emphasizes that one cannot understand the true state of a saint by external observations like their caste, behavior, or what they eat, as their reality is always beyond such things. This is illustrated by the story of a Yoga practitioner who came to see Baba. This practitioner, hoping for a profound spiritual experience from the "King of Yogis," was instead confronted with the sight of Baba simply eating bread (bhakar) with onions. The text also notes that while Baba was seen as an Avatar, he called himself a servant of God, further highlighting that a saint's inner state cannot be judged by conventional standards.
