Based on Chapter 51, what is the significance of meeting a Sadguru and listening to the Sai Charitra?

According to the teachings in Chapter 51, meeting a Sadguru is a profound event that occurs due to the "merits of past lives" and the grace of the Supreme Lord. This encounter is said to strengthen the bliss of the disciple. The chapter also emphasizes the purifying power of the Guru's stories. It states that by listening to the Sai Charitra, "both the listener and the speaker become pure." This sacred act sanctifies the ears of those who listen and the mouth of the one who narrates, as mentioned in the introductory verses of Chapter 51.
