What metaphors does the author use in Chapter 25 to explain the nature and purpose of the Shri Sai Satcharitra?

The author employs several beautiful metaphors in Chapter 25 to convey the spiritual significance 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 shelter from the 'heat of worldly existence.' He further compares the life story to a 'Somakant' or Moonstone, from which the 'lunar nectar of Sai's tales' flows. In this metaphor, the devotees are likened to thirsty 'Chakora birds' who can drink this nectar to their heart's content. Ultimately, the purpose of these holy stories is to 'burn away the sins of the Kali age' for attentive listeners.
