How does the author of the Shri Sai Satcharitra frame the importance of the stories he is about to tell, specifically leading into the tale of Damu Anna?

In Chapter 25, the author prefaces the story of Damu Anna by describing the entire Shri Sai Satcharitra as a "Shed of Nectar-like Sai Stories" provided by Sai's grace to help devotees ward off the heat of worldly existence. He urges the listeners to engage with an unreserved and focused mind, stating that these holy stories of Sai burn away the sins of the Kali age. He introduces Damu Anna's story as a pure and novel tale that will demonstrate how the Guru-Mother is an "Ocean of Mercy" and fill the listeners' hearts with joy.
