What is the stated purpose and effect of listening to the stories from Sai's mouth, as explained in the prelude found in Chapter 47?

According to the introduction in Chapter 47, the stories narrated by Sai are supremely holy and have a profound, purifying purpose. Listening to them is said to sever the bonds of Karma for all listeners, whether they are wise or ignorant. The text encourages listeners to focus on the inner meaning and moral of these accounts to achieve the fulfillment of their purpose. As mentioned in Chapter 47, hearing these wondrous stories can make listeners forget their bodily consciousness and be overwhelmed with divine love, bringing peace to those weary of worldly life, which is presented as the greatest possible gain.
