How does the author describe the nature and origin of the Shri Sai Satcharitra in the prelude to Damu Anna's story?

In Chapter 25, the author humbly states that his intellect was endowed with courage and knowledge by Sai Baba Himself, suggesting the book is a work of divine grace rather than his own audacity. He describes the Shri Sai Satcharitra as Sai's own record, created for the salvation of devotees. The life story is likened to nectar-like "Prasad" from the Saint's feet. The text is poetically called a "Shed of Nectar-like Sai Stories" to help devotees ward off worldly existence, and a "Moonstone" from which the nectar of Sai's tales flows, satisfying devotees like thirsty Chakora birds.
