If a saint's body dies, how can it be said that they are beyond death? What does the scripture mean by this?

Chapter 43 addresses this apparent paradox by distinguishing the saint's true self from their physical form. The body is described as merely an adjunct, and its death is its natural state. The text uses a powerful analogy, comparing a saint's passing to a solar eclipse. For the observer, the sun appears to be eclipsed, but this is a "defect of vision"; the sun itself is unchanged. In the same way, as Chapter 43 clarifies, the death of a saint's body is an illusion to the onlooker. The saint, being one with the Supreme Brahman, has no consciousness of the body and is untouched by its physical end.
