What does Chapter 21 of the Sai Satcharitra teach about the prerequisites for encountering a holy person?

Chapter 21 explains that encountering Saints and Sages is not a common occurrence but rather a sign that one's good fortune has dawned. The author uses his own past experience to illustrate this principle, stating that even if a saint is nearby, a sinful or unfortunate person cannot see them. The text emphasizes that the company of Saints is not accessible to the unfortunate and is made easy only when God’s grace is present. Without this grace, attaining such a union is considered very difficult, as mentioned in this chapter.
