What is the deeper meaning behind the statement in Chapter 23 that a saint's true state cannot be understood by their caste, behavior, or what they eat?

This statement in Chapter 23 offers a significant philosophical insight, cautioning against judging spiritual beings by external or worldly standards. The chapter explains that a saint's true state is "always beyond such things." This is illustrated by the story of the Yoga practitioner who is perplexed to see Sai Baba eating bread and onions, an act that defied his preconceived notions of a great Yogi. The teaching implies that external markers like caste, specific behaviors, or diet are superficial and do not reflect the saint's inner, transcendent reality. The incarnations of saints are a grace of the Almighty for salvation, and their essence cannot be grasped by such mundane observations.
