How does the story of the Yogi and the onions in Chapter 23 illustrate Sai Baba's teaching that a saint's true state is beyond external appearances?

Chapter 23 powerfully connects Sai Baba's teachings with a practical example through the story of the Yogi. The chapter first establishes that one cannot understand a saint's true state by external factors like their caste or what they eat, as their reality is always beyond such things. This principle is then vividly demonstrated when a Yoga practitioner, who had studied the shastras, develops a strong doubt about Baba's spiritual prowess upon seeing Him eat stale bread and onions. As recounted in this chapter, Baba, being omniscient, dispels the Yogi's misconception by addressing his unspoken thought about digestion. This incident proves that Baba's simple meal had no bearing on His enlightened state, reinforcing the teaching that a saint's inner reality transcends outward conduct and appearances.
