According to Chapter 21, what determines a person's ability to meet and benefit from a Saint?

Chapter 21 teaches that meeting a Saint is not a matter of chance or simple proximity, but is determined by destiny and divine grace. The text states that "Unless good fortune dawns, One does not encounter Saints and Sages." It emphasizes that even if a Saint is nearby, a sinful or unfortunate person cannot truly 'see' or connect with them. The author's own failure to visit Pir Maulana is presented as a prime example of this principle. Ultimately, as Chapter 21 clarifies, the company of Saints is not accessible to the unfortunate and this union is only made easy when God's grace is present.
