What philosophical concepts does Chapter 26 of the Sai Satcharitra introduce regarding the nature of reality and the role of the Guru?

Chapter 26 explains that the physical world and the universe are an illusion, or Maya, much like a city reflected in a mirror. It teaches that this entire visible world is illusory and will dissolve with the arrival of true knowledge. The text states that from the Creator Brahma down to a blade of grass, everything is a display of Maya and lacks independent existence outside the Self. According to this chapter, true knowledge, which dispels this illusion and reveals the light of non-dual bliss, can only be granted by a Guru. The Guru is presented as essential for helping a disciple realize the self-luminous and eternal nature of the Self.
