What is the main principle that Chapter 21 aims to demonstrate about meeting saints, and how does it use the author's own life to prove it?

The central principle presented in Chapter 21 is that attaining the company of Saints and Sages is not possible for the unfortunate and is only easy when God's grace is present. To prove this, the author narrates his own experience from his time in Bandra. Despite being a Magistrate in the same city as the famous Siddha, Pir Maulana, and being constantly urged to visit, he never went due to his own pride. He uses this personal failure as a direct example, stating that when "ill-luck stands in the way," one fears even their own shadow and cannot see a saint even if he is right beside them. This illustrates that divine timing and grace are essential for such blessed encounters.
