According to Chapter 32, why is the story of Sai Baba meeting his Guru considered so significant?

The story of Sai Baba's encounter with his Guru in the forest is presented as an event of supreme importance in Chapter 32. The text describes it as a "sweet incident narrated by Baba himself from his own mouth" and a "supreme wonder." Its significance lies in its power to grant devotion, faith, and liberation to those who hear it. The chapter emphasizes that the words from Sai's mouth, like this story, destroy sins and afflictions, similar to how the sight of the Ganga river does. It is considered so potent that listening to it can cause one to see their own Guru.
