According to Chapter 21, what are the necessary conditions for a person to be able to meet a Saint?

Chapter 21 teaches that encountering a Saint is not a simple matter but is dependent on one's destiny and divine will. The text clearly states that the "company of Saints is not accessible to the unfortunate" and that such a union is only easy to attain when God's grace is present. The author uses his own experience of avoiding Pir Maulana to demonstrate this principle, noting that "one fears one's own shadow when ill-luck stands in the way." Therefore, the key condition for meeting a Saint is the dawning of good fortune, which is itself a sign of divine grace.
