It seems strange that Baba knew the contents of Damu Anna's letter before it was read. How did the text describe this event?

The event is portrayed as a demonstration of Baba's omniscience. Before the letter was read, Baba's words already mirrored its contents, prompting Shama (Madhavrao) to exclaim, "Whatever You are speaking, That is the exact meaning of the letter; these are Damu Anna's words literally." Shama marvels at how Baba seems to stir up commotion in devotees' minds only to draw them closer. However, when confronted with this, Baba humbly deflects, as noted in Chapter 25, saying, "Arre Shama, read it, read it! Why do you think my words are the truth? I am just as I am. I just speak whatever comes to my mind."
