What philosophical concepts about reality and illusion are presented in Chapter 26 of Sai Satcharitra?

Chapter 26 of the Sai Satcharitra delves into the nature of reality by explaining that the entire physical universe is an illusion created by Maya, much like a city reflected in a mirror. The text states that from the Creator Brahma down to a simple blade of grass, everything is imagined and does not have an independent existence outside of the Self. This illusory world, which is compared to mistaking a rope for a snake due to ignorance, dissolves only when one attains true knowledge through the grace and words of a Sadguru. This awakening reveals the self-luminous and eternal nature of the Self.
