According to Chapter 26 of the Sai Satcharitra, what is the nature of the physical world and how is true reality understood?

Chapter 26 explains that the physical world and the entire universe are ultimately an illusion created by Maya, much like a city reflected in a mirror or a dream that vanishes upon waking. The text states that this visible world is imagined and has no independent place outside the Self. True knowledge, which dissolves this illusion, is realized when the time for awakening arrives through the Guru's word. It is emphasized that in the world, only the Guru is capable of granting the disciple the knowledge of Truth, which reveals the Self to be self-luminous and eternal.
