Can you explain the nature of the Self as described in Chapter 37, particularly in contrast to the visible world?

Chapter 37 describes the true Self as something that manifests effortlessly once all bondage is destroyed, much like the sun shines when clouds disperse. It is positioned as the ultimate reality, distinct from the transient visible world. The text advises that "All that is visible must necessarily be considered as non-existent," comparing it to a dream that disappears upon waking. The Self is described as being beyond concepts of existence and non-existence. It is devoid of all specific qualities, being eternal, ancient, unborn, and changeless, all-pervading like the sky and free from decay, birth, and death.
