According to the introduction of Chapter 51, what are the purifying effects of engaging with the Sai Charitra?

Chapter 51 eloquently describes the sanctifying power of its own narrative. It states that by listening to the Sai Charitra, both the listener and the speaker become pure. The text poetically asserts that this process sanctifies the very senses involved: "the ears of the listeners and the mouth of the speaker are sanctified." This spiritual benefit is compared to other natural acts of grace, such as sandalwood soothing heat or clouds showering rain. Therefore, as presented in Chapter 51, the tradition of spiritual narratives like the Sai Charitra arises specifically to satisfy and purify the hearts and minds of the devotees who engage with it.
