What is the main teaching in Chapter 21 about why some people get to meet Saints while others don't?

The central teaching in Chapter 21 on this topic is that meeting a Saint is entirely dependent on divine grace and one's good fortune, rather than proximity or personal effort alone. The chapter states, "Unless good fortune dawns, one does not encounter Saints and Sages." The author uses his own failure to visit Pir Maulana as a prime example of how "ill-luck" can act as a barrier. The text drives this point home by concluding that the "company of Saints is not accessible to the unfortunate" and this sacred union is only made easy when "God’s grace is present."
