Chapter 5 mentions that the story of the Guru and disciple was made known by Mahalsapati. It also teases future narratives. Can you elaborate on the concept of non-duality and how the chapter bridges past events with future stories?

Chapter 5 delves into the advanced spiritual concept of non-duality, explaining that a truly wise person sees the entire universe as their own form. They have transcended the illusion of separation, a state likened to the impossibility of the sun entering darkness. As the source material from Chapter 5 states, this story of the Guru and disciple was conveyed by Mahalsapati. The chapter then acts as a bridge, concluding this narrative while pointing toward future ones. It explicitly mentions that subsequent stories will be "even more profound," touching on topics like the history of the mosque, the mystery of Sai's lineage, and how he experienced his devotees' sufferings.
