How does the author use metaphors to describe the spiritual significance of the Shri Sai Satcharitra?

The author uses several powerful metaphors in Chapter 25 to convey the spiritual value of the Satcharitra. He describes the book as a 'Shed of Nectar-like Sai Stories,' offering a place where devotees can find refuge from the 'heat of worldly existence.' He also compares the life story to a 'Somakant' or Moonstone, from which the 'lunar nectar of Sai's tales flows.' This nectar is meant to satisfy the spiritual thirst of devotees, who are likened to 'thirsty Chakora birds.' These metaphors emphasize that the book is not merely a biography but a source of divine grace and spiritual nourishment capable of burning away the sins of the age.
