Based on Chapter 26, what is the true nature of the Self, and how does it relate to the universe?

Chapter 26 of the Shri Sai Satcharitra presents a profound philosophical view on the nature of the Self. It teaches that the Self is self-luminous and eternal. In contrast, the entire physical world is described as a mere play and marvel of Maya. The chapter explains that all objects of the physical world and the entire universe are actually within oneself, unmanifest and woven into the soul. The text emphasizes that the entire "world-spread has no independent place outside the Self." This suggests a non-dualistic perspective where the universe is not separate from the Self but is an illusory projection that dissolves upon gaining true knowledge of one's eternal, self-luminous nature.
