What is the stated purpose and effect of listening to the Sai Charitra as described at the beginning of Chapter 51?

Chapter 51 begins by explaining the profound effect of engaging with the Sai Charitra. It uses analogies to explain its purpose, stating that just as sandalwood on the Malaya Mountains soothes intense heat, a tradition of spiritual narratives arises to satisfy listeners. The text, as found in Chapter 51, explicitly states that by listening to the Sai Charitra, both the listener and the speaker become pure. This process is said to sanctify the ears of the listeners and the mouth of the speaker, highlighting its purifying spiritual power.
