Based on the introduction to Chapter 36, what is the stated purpose and effect of narrating the lives of saints like Sai Baba?

The introductory part of Chapter 36 of the Shri Sai Satcharitra explicitly outlines the purpose and profound effect of narrating a saint's life. The text asserts that the greatness of saints is infinite and that listening to their stories is a path to spiritual welfare. As described in Chapter 36, these narrations are not mere entertainment but are likened to "the very water of self-bliss" that purifies the listener and speaker. The primary effect is the removal of "the fatigue and misery of worldly existence," leading to a state of happiness and a deeper thirst for devotion.
