What philosophical points does the narrator of Chapter 21 make about storytelling and spiritual encounters?

In Chapter 21, the narrator begins by establishing a philosophy on effective narration, suggesting that a speaker's words are futile if they do not deeply move the listener, causing 'the hair on the body' to stand on end or tears of joy to flow. He then connects this to spiritual matters by asserting that encounters with saints are not easily achieved. The narrator posits that 'unless good fortune dawns, one does not encounter Saints and Sages.' He uses his own past pride and failure to visit the Siddha Pir Maulana as a prime example, concluding, as detailed in Chapter 21, that the company of saints is only accessible when God’s grace is present.
