What is the stated purpose of relating the story about Das Ganu's difficulty with his scriptural commentary?

The narrator in Chapter 20 explicitly states the purpose of telling this particular story. The primary intention is to demonstrate "how the Maharaj [Sai Baba] provide[s] the solution without even speaking" when a devotee encounters a difficult passage while reading. The author emphasizes this point, saying, "This is the purpose of this story, to make the gist known to the listeners. This is my only intention; please listen with a dedicated mind." The narrative serves as an illustration of the Guru's subtle and profound grace, which can resolve complex intellectual problems in unexpected and seemingly effortless ways, reinforcing the idea that the Guru's help is indispensable for true understanding.
