What is the primary philosophical teaching presented at the beginning of Chapter 26 of the Sai Satcharitra?

The beginning of Chapter 26 of the Shri Sai Satcharitra presents a profound philosophical teaching about the nature of reality. It explains that the entire physical world and universe are essentially an illusion created by Maya, comparing them to a city reflected in a mirror. The text states that from the Creator Brahma down to a simple blade of grass, everything is a display of Maya. This visible world is described as illusory and dissolves only with the attainment of true knowledge, which, as the chapter emphasizes, can only be granted by a Sadguru. This awakening reveals the true self-luminous and eternal nature of the Self, which is otherwise mistaken due to ignorance.
