According to the initial verses of Chapter 51, what is the spiritual purpose and effect of engaging with the Sai Charitra?

The beginning of Chapter 51 poetically describes the purpose of spiritual narratives like the Sai Charitra. It uses analogies, comparing the text to sandalwood that soothes intense heat or clouds that shower rain to bring joy to the world, suggesting its role is to satisfy listeners. The ultimate effect, as stated in Chapter 51, is spiritual purification. The text explicitly claims that by listening to the Sai Charitra, "both the listener and the speaker become pure." This sanctification extends to the physical senses, as the ears of the listeners and the mouth of the speaker are also purified through the act of narration and listening.
