Can you explain the principle discussed in Chapter 21 about why some people fail to recognize or meet a Saint even when they are physically close?

Chapter 21 of the Sai Satcharitra elaborates on the principle that encountering a Saint is not a matter of mere physical proximity but is dependent on one's destiny and God's grace. The chapter states that "unless good fortune dawns, one does not encounter Saints and Sages." It goes further to say that even if a Saint is right next to someone, a "sinful person cannot see Him." The author uses his own past experience of not visiting the Siddha Pir Maulana in Bandra as a prime example, attributing his reluctance to "ill-luck" that stood in his way. This narrative reinforces the central point that the company of Saints is not accessible to the unfortunate and that this divine union is only made easy when God's grace is present.
