Chapter 49 mentions the author's motivation for writing. Can you explain what drives him to describe Sai's greatness despite acknowledging its inexpressible nature?

In Chapter 49, the author's motivation stems from an overwhelming desire to share the spiritual bliss he experiences. He acknowledges that Sai's Leela is inexpressible and the Sadguru's greatness is unfathomable, yet he "cannot remain still." The chapter uses a beautiful metaphor, comparing this spiritual knowledge to a "sweet delicacy." The author feels that if friends and virtuous people are not there to share it, the sweetness turns bland. This thought of sharing what he calls the "culinary arrangement of essence" took deep root in his soul, compelling him to write and complete the book for the benefit of all listeners.
