According to the narrator in Chapter 21, what is the primary prerequisite for being able to meet a Saint?

The narrator in Chapter 21 makes it very clear that simply being near a Saint is not enough to truly encounter them. He states that "unless good fortune dawns, one does not encounter Saints and Sages." The text emphasizes that the company of Saints is not accessible to the unfortunate, and this union is only made easy when "God’s grace is present." Otherwise, attaining this connection is considered very difficult. The author uses his own failure to visit Pir Maulana, despite being in the same city and being urged to go, as a personal testament to this principle, which he attributes to the "ill-luck" that was influencing him at the time.
