What is the main precondition for attaining the company of a saint, according to the teachings in Chapter 21?

According to Chapter 21, the primary precondition for attaining the company of saints is the dawning of good fortune and the presence of God's grace. The text explicitly states, "Unless good fortune dawns, One does not encounter Saints and Sages." It emphasizes that this union is not accessible to the unfortunate and is only easy when divine grace is active. The author uses his own past failure to visit a Siddha as proof, noting that "One fears one's own shadow when ill-luck stands in the way." Therefore, the key takeaway from Chapter 21 is that meeting a true saint is not a matter of personal effort or proximity alone, but a sacred event orchestrated by destiny and grace.
