Based on Chapter 26, what is the true nature of our Self, and how does it compare to the physical world we perceive?

Chapter 26 of the Shri Sai Satcharitra draws a stark contrast between the nature of the Self and the physical world. The Self is described as 'self-luminous and eternal,' representing the ultimate, unchanging reality. In contrast, the physical world, from the Creator Brahma down to a simple blade of grass, is described as a 'play and a marvel of Maya'—an illusion. The text explains that this visible world is illusory and has no independent place outside the Self, much like a dream that dissolves upon waking. While the universe appears manifest as moving and non-moving objects, it is, in reality, unmanifest and woven into the soul. This chapter teaches that realizing the eternal nature of the Self and the temporary, illusory nature of the world is the goal of spiritual knowledge.
