How does the text define death and distinguish between the manifest and unmanifest states?

The text offers a philosophical perspective on life and death, moving beyond a purely biological definition. As explained in Chapter 37, that which comes into form from the unmanifest is referred to as the 'manifest' state, which we perceive as life or existence. Conversely, when this form dissolves and enters the unmanifest state once again, it is this transition that is called 'death'. This concept reframes death not as an end, but as a return to an unmanifest source, suggesting a cyclical nature of existence rather than a linear path with a final termination.
