Chapter 26 of the Satcharitra talks about Maya and the universe being an illusion. Can you explain this philosophical concept?

According to the teachings in Chapter 26 of the Sai Satcharitra, the entire physical universe is considered an illusion created by Maya, much like a city reflected in a mirror. The text explains 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 illusion is compared to mistaking a rope for a snake due to ignorance. The chapter states that this visible, illusory world dissolves only when true knowledge is attained through the words of a Sadguru, leading to the realization of non-dual bliss.
