What kind of metaphors does the author use to describe the Shri Sai Satcharitra, and what does he say its ultimate purpose is for the reader?

In Chapter 25, the author employs beautiful metaphors to convey the essence and value of the Shri Sai Satcharitra. He describes the book as a 'Shed of Nectar-like Sai Stories,' offering devotees a place to serve Sai and find refuge from the 'heat of worldly existence.' It is also likened to a 'Moonstone (Somakant)' from which the 'lunar nectar of Sai's tales flows,' meant to satisfy the spiritual thirst of devotees just as nectar satisfies thirsty Chakora birds. The ultimate purpose, as stated in this chapter, is to serve as a form of grace from the Saint's feet, to awaken devotees, to grant salvation, and for its holy stories to burn away the sins of the Kali age for those who listen with a focused mind.
