What does Chapter 23 say about judging a saint's spiritual state and the purpose of their incarnation on earth?

As detailed in Chapter 23, one cannot understand the true state of a saint by observing external factors like their caste, behavior, or what they eat. Their inner state is always beyond such superficial things. This is exemplified by the Yogi who initially doubted Baba upon seeing Him eat onions. The chapter clarifies that the incarnations of saints occur on this earth out of benevolence, as a grace of the Almighty, specifically for the salvation of 'dull-witted souls.' It is only when a person has accumulated merit (Punya) that a desire arises in their heart to hear the stories of these saints, which is a path to attaining happiness, contentment, and the calming of calamities like sorrow and delusion.
