What does Chapter 21 teach about the conditions necessary for encountering Saints?

Chapter 21 explains that meeting Saints and Sages is not a simple matter but is dependent on one's fortune and divine will. The text states that good fortune must dawn for such an encounter to happen, and without God's grace, this union is difficult to attain. It emphasizes that even if a Saint is physically close, a "sinful person cannot see Him." The author uses his own failure to visit Pir Maulana, as narrated in this chapter, to demonstrate how ill-luck can act as a barrier, making the company of Saints inaccessible to the unfortunate.
