According to the text, what is the spiritual effect of listening to or speaking the Sai Charitra?

According to the introductory verses of Chapter 51, engaging with the Sai Charitra has a profound purifying effect on individuals. The text explicitly states, 'By listening to this Sai Charitra, both the listener and the speaker become pure.' It further elaborates on this sanctification by mentioning that 'the ears of the listeners and the mouth of the speaker are sanctified.' The author of Chapter 51 uses several analogies to illustrate the purpose of such spiritual narratives, comparing them to sandalwood that soothes heat, rain that brings joy, or flowers that bloom for worship, suggesting that the tradition of these stories arises to provide spiritual satisfaction and purification to devotees.
