How does the author of the Shri Sai Satcharitra describe the book itself and its purpose for devotees?

In Chapter 25, the author describes the Shri Sai Satcharitra as far more than a mere collection of stories or a play on words. It is portrayed as the very grace and 'Prasad' from the Saint's feet. The text uses the metaphor of a 'Shed of Nectar-like Sai Stories,' inviting devotees to serve themselves to their heart's content to find relief from the heat of worldly existence. It is also compared to a Moonstone (Somakant) from which the nectar of Sai's tales flows, intended to satisfy devotees like thirsty Chakora birds. The ultimate purpose of listening to these holy stories is to burn away the sins of the Kali age.
