A state of severe existential danger stands at the center of the human experience when a person reaches the very edge of life. The primary approach among commentators is that this precarious moment is divided into two complementary aspects, detailing how different layers of human existence are affected as the end draws near.
The first aspect involves the soul drawing closer to the grave [מצודת דוד, אלשיך] or the underworld [ביאור שטיינזלץ]. A person finds themselves in immense peril, often before they have had the chance to fully grasp or understand their dire situation [מצודת דוד]. Alternatively, this descent reflects a deeply personal, subjective experience of feeling that death is imminent [ביאור שטיינזלץ]. On a spiritual level, the soul in this context is understood as the entity that will ultimately mourn over the physical grave after passing away [אלשיך].
The second aspect focuses on the core vitality of the individual. This refers to the basic life force or vital energy [מצודת דוד]. However, there is a contrasting view that this vitality actually represents a higher spiritual plane than the soul mentioned previously [אלשיך]. As this life force fades, it approaches the heavenly forces responsible for bringing death. Commentators unanimously agree that these forces are the angels of destruction [ביאור שטיינזלץ], the killing angels [אבן עזרא], or the direct messengers and powers of the Angel of Death [מצודת דוד, אלשיך].
Looking at the picture as a whole, a profound division emerges that encompasses the entire human being. The approach toward the grave represents the spiritual and emotional peril of the individual, while the fading life force drawing near to the angels of death signifies the ultimate physical danger of mortality [מלבי״ם].
